GTO, some consider it the most revered three letters among the Pontiac faithful. More than 40 years ago, the original Pontiac GTO launched the muscle car. The GTO legend continues and is enhanced by the 2004 model. It is not an exercise in nostalgia, but an update on the first muscle car concept and packs quite a punch.

For a bigger punch K&N Engineering has a Generation II 57-Series Fuel Injection Performance Kit (57-3044) for the 2004 Pontiac GTO 5.7L V8. K&N tests have shown an 18.54 horsepower gain at 5818 RPM with this intake.

By replacing the Pontiac GTO’s factory air intake assembly with K&N’s 57-Series Fuel Injection Performance Kit the engine gets cool, dense air with less restriction. The FIPK uses K&N’s high-flow, washable and reusable air filter (RF-1048) which performs up to 100,000 miles before service is required (depending on driving conditions).

“This was tricky because the engine compartment is not that big on the GTO,” said K&N Performance Kit Manager Bert Heck. “Our engineers built it and it has great power.”

K&N’s FIPK (57-3044) can be installed in 90 minutes or less with simple hand tolls and lasts up to 100,000 miles before service is required (depending on driving conditions). It also comes with the famous K&N Million Mile Limited Warranty.
