Has anyone bought a air foil for their TPI. Let me know what you thought about the air foil. Do you think its worth the $50.00 or should i save my money toward something else.

 

if you watch on Ebay, you can get the for $25-30

 

they dont give much of a power increase. i did this along with a few other free mods and gained practiclly nothing. however, if you never plan on going bigger than the stock TB, i would get it, as the design does smooth airflow. this mod falls into the "every little bit helps" catagory. if youre looking for a noticable power increase, do some exhaust work, the factory system is very restrictive

 

the exaust is already done. cat back with flowmaster muffler. i am planning on getting another tb maybe a 54 or 58 mm. so you don't think its worth getting with the stock 48 on it.

 

The airfoil showed a 1hp gain on an LT1. Its not worth $50. Check ebay and see if you can get one at half the price if it makes you happy to have it. Also, you say you plan on going to a 52 or 58MM TB. most aftermarket TB's already have one built into them. And a 58MM TB is usless unless you have a lot of horsepower.

 

If you're going to spend money on one, get eth SLP. It's the cheapest at $26 last time i checked, and will work just as well as any of the high dollar ones.

 

or if you are luck..BOTH not just one of your cars comes already equiped so you don't have to bother....hell if the K&Ns and the Airfoil add nothing i still well be happy....i personaly don't belive in buying these things....maybe the K&Ns b/c they clean better....right?
