TPIS AIRFOIL - $60 http://www.tpis.com/index.php?module...tegory=Airfoil

SLP AIRFOIL - $36 http://www.hawksthirdgenparts.com/in...OD&ProdID=1060


That is a $24 difference and I can't understand why one is more expensive than the other. They look exactly the same, so should I go with the SLP instead of the TPIS? Along with this I will be gutting my intake.

With an Airfoil and gutting of my intake. (K&Ns already installed) How much HP do you think I will gain?

 

the airfoil... a much debated part... some say useless peice some say worthwhile... i think they are pretty useless and at 36$ to expensive to buy and realize the fact.

dont think anyone has done back to back dyno pulls with one but i am guessing you wont notice it.... well you might think you do for a little while

 

if it smooths the track of the airflow it helps a higher rpms .......period

unless you have a motor that is making peak horsepower at 6500+ you may not see the benifits
