Thinking of buying some K&N Air filters for my 1987 Iroc 305tpi
I read that they increase about 1-4hp each filter as the 3rd gens have 2
How does this price look for each one ?

Just Wanna know other ways to increase horsepower, nothing to crazy in price wise either?

 

Just rememeber that 1-4 HP is max Dyno HP only felt at 5500 RPMs. Your not going to feel this upgrade.
