Any serious off-roader installs a snorkel intake on their JK Jeep Wrangler before heading off-road

The 3.8L V6 was based on Chrysler’s 3.3L narrow-angle 60-degree V6 engine, of which nearly 5 million of the smaller displacement engine had been produced. While the 3.8L (230.5 CID) V6 saw duty in various mini-vans, it was installed in only one Jeep model: the 2007 – 2011 JK Wrangler.

The 3.8L V6, code named the EGH, was manufactured in Chrysler’s Trenton, Michigan engine plant. The increase in displacement was achieved by both increasing cylinder bore and crankshaft stroke. The EGH featured a cast iron engine block with forged steel connecting rods and aluminum cylinder heads with a single central camshaft, roller tappets, pushrods, and overhead valves. Fuel delivery was by sequential multiple-port fuel injection.

From 2007-2011, JK Wrangler customers had to make do with the 202 horsepower EGH V6. However, in 2012 Jeep began installation of the Chrysler Pentastar 3.6L V6 engine, which boosted power to 285 horsepower, leaving owners of previous model years over 80 horsepower short of the new models.

The K&N AirCharger kit comes complete from snorkel to the intake manifold connection

The uniquely designed snorkel system that’s a key component of the K&N 63-1574 AirCharger system brings in outside air from an ideal location to allow you to ride your Jeep hard in extreme off-road conditions. Fresh air is directed through the low-restriction snorkel tubing and into a tough K&N roto-molded air box that contains a RF-1048 7.5-inch K&N high-flow air filter.

The Roto-Molded air box features a cover to allow for easy access to the oversized air filter

The K&N 63-1574 was designed for the following vehicles:

K&N 63-1133 is designed to improve throttle response and engine sound on Polaris 1000 UTVs

What separated the Polaris RZR from its competitors at the time was that the RZR was sold straight off the dealers' showroom floor with high levels of off-road performance. The Polaris Ranger RZR, typically shortened in conversation to the Polaris RZR, was the first true “out of the box” sport UTV available.

Building upon the success of the original model, Polaris has spent the last decade improving and expanding the RZR product line. A common feature among all RZR models, though, is the disposable (and expensive) pleated paper air filter fitted to the OEM air box. While a disposable paper air filter is efficient at trapping dirt up to a point, it leaves a bit to be desired in terms of performance, longevity, and cost.

The custom fabricated intake completely replaces the OEM unit and provides better air flow

K&N developed the 63-1133 Aircharger® performance air intake systems specifically for select 1000 series RZR models to increase power and torque, as well as reduce maintenance costs. This air intake system is an easy to install, bolt-on upgrade which replaces the entire restrictive original equipment air box and filter.

K&N's Polaris Ranger RZR XP 1000 air intake features a conical air filter and free-flowing aluminum intake tube which deliver air an increased flow of air into the engine’s throttle body for a guaranteed power gain. The intake system also features a custom air box designed to shield the air filters from engine heat. Beyond gains in power the performance air intake kit also improves throttle response and engine sound.

And while initially a little more expensive than the OEM disposable paper filters, the conical K&N air filter is washable and reusable. Further, not only is the filter designed to dramatically reduce intake air restriction but also provides excellent protection from harmful dirt, dust, and contaminants.

K&N filters are constructed with strong pliable rubber flanges to absorb vibration and shock

K&N Aircharger air intakes for select Polaris RZR models provide increased horsepower and better throttle response. When dyno tested, the Aircharger performance air intake systems increased output by an estimated 3.3 horsepower at the drive wheels.

This air intake is relatively easy to install - taking just 90 minutes or less - using existing factory mounting points and common hand tools.

Jimmie Johnson celebrating his win at the Food City 500 at Bristol Motor Speedway

“Yeah, just a really solid performance all day long, great pit stops,” Johnson said. “Same thing at Texas. I think that was the piece we were lacking to start the season. Don't know why, don't know what it was, but our cars have been very capable of running up front, and it's been nice these last two weeks to execute from the start of the race qualifying. Was saved by the rain this week and the week before. I spun out after I took the flag”.

This was Johnson’s 82nd career win, which puts him within one for sixth place on the all time career wins list. The win was also the second career win for Johnson at Bristol Motor Speedway. Johnson did not lead until the 394th lap of the race, and eventually led three times for a total of 81 laps.

“I know we won here one other time, but I think from a consistency standpoint and competitive standpoint, this is the best we've ever been, and I've been looking and trying to figure this place out, and I've come here with the identical race car that Jeff Gordon wins with, and I run 15th,” Johnson said. “That's where a lot of that emotion came from is more in the personal category today and getting that win”.

Clint Bowyer came in second place, finishing just 1.199 seconds behind Johnson. This was Bowyer’s best finish since finishing in second place in 2013. Bowyer is still looking for his first win since 2012 at Charlotte. This was Bowyer's fourth top 10 finish this season and his 11th at Bristol Motor Speedway.

Drivers led by Martin Truex Jr stopped for a pit stop

Kevin Harvick came in third place, who was passed by Bowyer, his teammate, on lap 485.

“We just needed track position,” Harvick said. “I think we showed how fast it was there on no tires and kind of able to hold our own. A good weekend, and we’ll just keep going."

Kyle Larson, who finished in sixth, leads the Monster Energy NASCAR Cup Series Standings with 360 points and 7 playoff points. Chase Elliott is in second place with 333 points. Martin Truex Jr is in third place with 323 points and 10 playoff points. Brad Keselowski, Jimmie Johnson, and Martin Truex Jr are tied for the lead the in the current playoff standings with 10 points.

The next race in the Monster Energy NASCAR Cup Series will be at the Toyota Owners 400 at Richmond International Raceway.

Luke Bogaki won the K&N Spring Fling Million in Las Vegas for the first time in his career.

Bogacki beat Michael Pennington in the final round by 0.0003 seconds. They both had almost identical reaction times. Pennington was two thousandths of second faster off the line at 0.012 seconds. Bogacki left the starting line at 0.014 seconds. Bogacki and Pennington raced neck and neck down the strip with Bogacki winning by a nose.

“That’s kind of typical for the racing that we do,” Bogacki said. “I look at those as coin flips basically. They can go either way.”

Bogacki said he is constantly asked how to win those close races. He says luck plays as much as role as anything.

“It’s a skill to put yourself in that position where the races are close, but it’s just a coin flip,” Bogacki said. “I was fortunate to come out on the right side of it.”

After the race, Bogacki said it took a while for it to sink in that he won.

“I knew when we hit the finish line that it was super close and I was fairly confident that I hit the dial in,” Bogacki said. “It’s one of those where you look up at the scoreboard and hold your breath. It could go either way.”

Luke Bogacki won $230,000 in the K&N Spring Fling Million in Las Vegas.

“He’s such an awesome competitor,” Bogacki said. “You kind of expect it. It was no surprise to see him there. Certainly no shock that we had such a close race.”

Bogacki advanced to the quarterfinal round with five other drivers. Val Torres Jr., Bobby Dye Jr., Lane Dicken, Pennington, and Randy Biddle were the other quarterfinalists. Bogacki earned a bye in the semifinals and awaited the winner of the race between Biddle and Pennington.

He was able to earn the bye by having the quickest reaction time of the three winners in the quarterfinals. It also came with a $60,000 bonus.

“I had the best winning reaction time of six cars out of the three winners,” Bogacki said. “The way that shook out, that was the most lucrative single win light by a wide margin.”

Bogacki won $230,000, a trophy, and a limo ride to the Cosmopolitan Hotel on the Strip as part of the Spring Fling championship.

“The margins are razor thin,” Bogacki said. “You get used to winning or losing by a thousandth of a second. In my career, I have accomplished more than I ever dreamed that I would.”

Bogacki said winning the K&N Spring Fling Million was like completing a career grand slam in drag racing. He has won a U.S. Nationals title, an NHRA World Championship, and a Jeg’s All Star event. The Spring Fling Million completes the big four events.

“If there was one bucket list item left to achieve, it was actually winning the Million,” Bogacki said. “It’s the last thing that I have to do. The field is so deep and so strong that you never know when it’s going to happen or if it’s going to happen. I feel that my career is complete and super grateful that it fell together.”

Dangerously high winds postponed qualifying on the Thursday before the elimination rounds. The drivers had a full day of racing to whittle down the field to the final day of races.

Luke Bogacki compared winning the K&N Spring Fling Million to hitting a grand slam in baseball

The next K&N Spring Fling event is at Galot Motorsports Park in North Carolina.

“I thought it was really special to come out on top of the event in the K&N Filters dragster at the K&N Spring Fling Million,” Bogacki said. “They just do so much. Forget what they do for me and my race team, they do so much for the sport and drag racing. Case in point, sponsoring that event. It’s just an honor on my end just to represent them.”
