More horsepower, torque, and a touch of class for Duramax Diesel engines with Performance Air Intake System 77-3077KP, from K&N

2011 marked significant changes for the Isuzu designed Duramax diesel engine used in the Chevrolet Silverado and GMC Sierra 2500 / 3500 HD pickups. General Motors made changes to enhance durability, lower emissions, and at the same time increase power output. This latest generation of the Duramax diesel received the engine code LML and replaced the outgoing LMM engine. While GM did their homework to produce a solid engine for their heavy-duty line of pickups, K&N engineers saw the potential for even more improvement.

K&N Performance Air Intake System, 77-3077KP, from K&N Filters features a special 6-ply high-flow air filter for demanding environments encountered by Duramax Diesels

K&N 77-3077KP Performance Air Intake System is expert-engineered and guaranteed to increase horsepower and torque. It replaces the restrictive factory system with a free-flowing, mandrel bent aluminum air intake tube to help minimize restriction, straighten, and increase airflow to the engine. The mandrel bent aluminum intake tube is finished with a chrome-like appearance for a custom look under the hood. The 77-3077KP incorporates a heat shield which helps guard air entering the engine from ambient heat.

The 77-3082KP intake system’s bright intake tube looks good under the hood of this 2014 Chevrolet Silverado

These days a full-size pickup truck or SUV does more than just throw a mean hook. A modern full-size pickup truck or SUV must have refined interiors with modern-day technology, a comfortable platform that is refined on-road, yet rugged off-road and it must have style. In other words it has to float like a butterfly but sting like a bee. Some might think this isn’t doable, but General Motors seems to have stepped on the scale and made weight with the fully-redesigned 2014, 2015 and 2016 Chevrolet Silverado, Tahoe, Suburban, their GMC brethren the Sierra, Yukon, Yukon XL and the luxurious Cadillac Escalade. While the 5.3 liter EcoTec V8, and the available 6.2L V8 pack a punch in stock form, who doesn’t want to become the undisputed champion? As they’d say in boxing, installing a K&N 77-3082KP Performance Air Intake System can follow up an already ample punch with a one-two combo. The 77-3082KP intake system is a real knock-out, packing both added performance and increased style.

Ben Rhodes had the fastest qualifying time in the NASCAR K&N Pro Series East race at Bowman Gray Stadium in North Carolina

Rhodes ran a nearly flawless race at Bowman Gray. He led 151 of 152 laps in the NASCAR Hall of Fame 150. The race ended with a green-white-checkered flag finish. Ben Rhodes increased his lead in the NASCAR K&N Pro Series East standings to 49 points over Gray Gaulding.

Bowman Gray Stadium was packed with NASCAR K&N Pro Series fans who watched Ben Rhodes lead 151 of 152 laps

“That was a little tricky there,” Rhodes said. “I was afraid something might happen. I was afraid I might get moved up. If it wasn’t (Gaulding) it was going to be somebody else. That’s what this track creates. Just lucky we got to hold him off there at the end for the win and Daniel Suarez as well.”

The only time Rhodes lost his lead was in the final restart. Daniel Suarez passed him on lap 150, but Rhodes regained the lead for the final two laps of the race.

Rhodes won the NASCAR K&N Pro Series East race at Greenville Pickens Speedway in North Carolina on March 22 and was the overall winner in the NASCAR K&N Pro Series race at Iowa Speedway on May 17.

“It hasn’t really sunk in yet,” Rhodes said. “I’m sure once we go back to the shop and talk to these guys and just sit down, it will start sinking in. I’m kind of elated right now. Just really happy about our accomplishment right now.”

Suarez held on for second place. While Rhodes ran up front the entire night, Suarez had to rally through the field. “It was fast and with some luck, we drove all the way back to the front with a happy face and a second-place finish,” Suarez said.

Suarez started in the 20th position in the 20-car field after hitting the wall in qualifying.

“It was pretty difficult,” Suarez said. “In the beginning, we started in the back. Early in the morning we had one of the best race cars out there. In the qualifying we had some trouble with the rear brakes and we hit the fence. After that we decided to work on the car and start at the back to be more prepared for the race.”

Rhodes and Gaulding battled for the lead early in the race. Rhodes started on the pole. Gaulding started in the inside of Row 2. But Gaulding faded in the closing laps of the race and finished in sixth place. It was Gaulding’s fourth top-10 finish in seven NASCAR K&N Pro Series East races.

Austin Hill finished in third place in his first K&N Pro Series race at Bowman Gray Stadium. It was his fifth top-five finish of the season.

“It was really wild, that’s for sure,” Hill said. “We had a really good car at the very beginning of the race. It was really good. It started falling off, getting a little tight running through the center. Coming home with a third place is definitely exciting. I just want to win.”

Brandon Jones came in fourth place, followed by Ronnie Bassett Jr. in fifth at Bowman Gray.

The next race in the NASCAR K&N Pro Series East is the Pensacola 150 at Five Flags Speedway in Florida on June 13.

Chris Ferguson is no stranger to lining up against other super late model drivers. In fact, he has five years of racing in this particular class under his belt. However, this season is a little different. He’ll see new faces and travel to unfamiliar venues. Ferguson will be experiencing his first season in the National Dirt Racing League.

Chris Ferguson relies on K&N products to navigate the dirt ovals of the NDRL series

One would suspect that the anticipation was practically overwhelming to the driver when he rolled into Phenix City, Alabama, to race in the Bama Bash, his first race of the season. But his actions lent to a totally different perspective. A little apprehensive at first, it didn’t take long for the driver to find his groove. With 20 laps to go , he muscled his way into the top five.

Things were looking promising when the driver moved into the top three. But bad luck eventually reared its ugly head. He lost his stronghold on those behind him, upon having a flat. However, it quickly became evident that quit was not in Ferguson’s vocabulary. Getting the Warrior 1G back in working order, he pressed onward, finishing 11th in a field of 25.

When asked about his confidence level prior to the race, Ferguson said, “I knew we had a great car, but I hadn’t raced since last November. So I was a little timid at first. However, once I got back in the seat, I knew we had a great shot at running good; so my confidence was high.

“There was some pressure, with it being such a big race,” he continued. “All of the country’s best drivers were there with over 40 cars trying to make the 24 car starting field. It was tough to even make the main event. The most pressure was the fact that the best of the best were there, racing door-to-door with me. So I knew I had to drive the best I could.

With the first race of the 2014 season behind them, Ferguson and his crew headed to the Smokey Mountain Speedway, at Maryville, Tennessee; where they would race in the Tennessee Tipoff. With what he considered a reputable run at the Bama Bash in his rearview mirror, the driver had no intentions of doing anything other than making a showing in race number two of the season as well.

A good performance during his initial race of the season was more than enough to boost his confidence. However, Ferguson was even more stoked to know that dirt super late model hall of fame member; Freddy Smith would be in their corner. “He no longer races,” explained, Ferguson. “But he comes to races with us, to consult and help us out on the road. Freddy is from the same part of North Carolina, and my family has always known him.”

Earning the tenth place spot in the $7,500.00 to win preliminary event, the driver returned the following day with aspirations of success. At the waving of the green flag, engines revved, the air permeated with the aroma of exhaust and the battle was underway. The driver wasted no time getting into the mix, and at the race’s end, crossed the finish line in eighth place.

With many races ahead of him, Chris Ferguson is looking forward to the future. Ranked 10th in the points standing early on, the driver is acutely aware that the potential for a stellar season is certainly within his reach.

Although his skills will play an important role in the overall outcome of the season, the driver is also mindful that maintenance will also prove an essential element of success. That in mind, he and his crew will depend upon K&N products to keep his engine running contaminant free.

“I use the K&N 6 inch washable and reusable air filters,” he explained, “along with their fuel and oil filters. I also use K&N cleaning supplies to clean our filters. K&N makes the best filters on the market."

“The fact that we can use about five air filters to run around 60 races a year is unbelievable,” he continued. “We put over 2,000 laps on our engines, and our K&N filters stand just as long. I’ve never had issues with any of our K&N products, and we’re proud to say that our team will always be a K&N customer.”

With a high confidence level and the backing of excellent products, Chris Ferguson is apt to experience a memorable 2014 season. When asked what his fans can expect throughout the remainder of the year, Ferguson concluded, “A lot of traveling and hopefully, more wins. We just knocked out a $10,000.00 win in Virginia and followed it up with a $5,000.00 win in Tennessee this past weekend. We plan to continue following the the National Dirt Racing League.”
