Hey guys i see a few of yous have airfoils. is it worth the money?I saw one for about 60$what kind of difference does it make?

 

Get an SLP. They run about 29.99

 

They do make difference, even if some say they don't.

87 IROC-Z 350 TPI
84 TRANS AM 305 H.O.

 

I got the SLP the other day on sale, probably install it tomorrow and I'll let you know if it was worth it. I'm not expecting anything noticeable, but every little bit adds up.

 

I didn't really notice a difference, and I've used both the SLP and the JET (which I'm using now), but every little bit helps. Suppose I should be able to feel a SOTP diff when I finish my custom cold air kit to free up the intake.

I didn't notice any SOTP difference, but someone around here did a flow comparison and it increased the air flow, so it does do something whether you feel it or not.

Like was said above, every little bit helps. I can't say I felt a difference with my Jet airfoil, but I know that it had to help some.

thanks for the info guy, one other thing was that 29.99 CAN or US?

 

U.S.

 

Be aware that ordering from SLP in the States will cost you big bucks for shipping to Canada. I ordered the airfoil from SLP... paid $29.99 USD, $7.95 USD for shipping, all charged to Visa - that works out to about $60 CAN. Great. However, when the part came to my door, it was shipped via UPS courier, and I had to pay an ADDITIONAL $40 CAN brokerage fee!!!!! SO that $29.99USD part cost me $100 CAN. That is WAY too much - buy the part locally for $60 if you say you can find it hree in Canada.
