Product Reviews    Review part 66-1401XP

I have a 66 Mustang with a .030 bored 289 fairly well done with AFR heads. When doing a dyno tune, and after doing some primary jetting on the 750 Demon carb we did two pulls. When we put the K&N X-Treme lid and the 14 K & N element back on I had a increase of 17.9 hp and an amazing 22.6 ft. lb. tq increase due to the fact that cleaning the air and directing the air into the carb properly as they are designed to be doing. I'm Amazed!
