Led by Grant Enfinger, who dominated 2015 with more wins, poles, Top 5s, and Top 10s than any ARCA racer, the all-new ARCA Ilmor 396 engine won every ARCA race in the 2015 season. Enfinger swept the first three races of the season and overcame crashes at the next three to win three more times and take the championship in a landslide – but it wasn't just him.



Holley EFI that controls the fuel and ignition systems, there's a Holley throttle body, fuel pump, fuel rails, and injectors. Hooker BlackHeart headers, ACCEL LS ignition coils & spark plug wires, Earl's plumbing, and the revolutionary new Holley HydraMat fuel reservoir system complete the package that's already become a must for EFI engines. As the season progressed and cars powered by the new engine package won race after race, more and more teams scrambled to get them. By year's end, 13 different drivers, including nine first-time winners, scored with Ilmor power: Enfinger, two-time winners Mason Mitchell and Ryan Reed, series runner-up Austin Wayne Self, Kyle Weatherman, A.J. Fike, Ken Schrader, Blake Jones, Travis Braden, Cole Custer, Ross Kenseth, Todd Gilliland, and former Daytona 500 winner Trevor Bayne.
