    Good price great product

    Bought this kit for an early 99 and everything came quickly and all parts were included. Very easy install. Best thing I've done to my truck so far, and the added turbo whistle is a nice bonus.

    Bring 'Tha Noise!!

    Just installed on my stock late '99. Kit is of very good quality & was easy to install with no trimming. Oh yeah, it sounds KILLER!! Turbo spools much faster down low and and pulls a little stronger in the upper rpm's. Hopefully I see a few bonus mpg's too.

    Thanks Clay & co! I'll be back for more.

    Breathe Turbo!

    This is the best intake kit you can buy for your 7.3. It allows the turbo to spool quicker generating power through a wider range of the engine RPM. The install only took 30 minutes or so, with no cutting required on the 94-98.

    air filter

    Easy enough to install and figure out. If you have a 7.3L with 2 batteries, be prepared to cut the plastic tray that holds the left battery. They didn't include that step in the directions...

    Great product

    Love this product. Been running these filters for 2 years and have only been happy. Push 4 more psi of boost than stock intake. Breathes great, more power, and sexy whistle!
