Put one on my son's 02 Ranger...........messed up the computer. Took it back out and the computer settled back down.

 

Those are worthless. I would love to be the guy who invented it.......what a killing he's making on something that does virtually nothing.

 

Thought so!! Thanks....

 

we must need a law to avoid selling fake parts like that

 

Seem like someone on the forum answered another thread with two words "snake oil".

 

its worthless, even gives you less performance as it blocks some air flow, will lose a few tenths in quarter mile, want gas mileage use pulstar plugs, mobil 1 synthitic oil,remove, jack spare, remove muffler, shelf or any weight you can CAI intakes help also,want more go to tire rack get the lightest 16-17 in wheel and tire you can afford . NO to 18=20s will give worse MPG, low rolling resistace tires help also, i run contipro contacts V rated, they were the lightest you can buy , nice of tire rack to list weights. i get 2 MPG better , ride is loud, even with stock resonater, but i dont care power and mpg is what its all about, also up north the crappy winter blended gas we have in ny reduced mileage up to 10 percent, cant wait for spring
