On my Evo 8 I have an aluminum intake with the Maf and a 4.5inch inlet cheap cone filter(see pic) I have been looking at K&n air filters but don't know which ones to get. What are you guys using?

 

Take a look at the AMSoil dry filters before immediately deciding on a K&N brand filter.

 

^ loving the Amsoil air filter here. Been running one pretty much since I saw Kracka's air filter shootout few years ago..

 

This topic has been beat to death

Amsoil filter all the way


Knn is not something I would run because while it flows well, they sacrificed a lot of its filtering capability.

Which filter are you guys using?

 

Perrin is my choice for the VIII/IX, but Amsoil is the runner up.

The Speed Element OMG filter is pretty popular, but my personal vote is also a Perrin filter.

Don't let the posts about the MAF sensor and oil scare you, just take a paper towel to it before install.

 

I was thinking of purchasing this one. It's an Injen/amsoil.

Which one do you get? The one on the box or the one next to the box?

 

I am sorry I think I am going with this Perrin

Should I go for it?

 

Do i need to retune? Lol

 

I think the change to the A/F is minimal if you're going from one aftermarket filter to another IMO.

 

Great! I just ordered it.

 

I'm looking to switch out of the ARC box as my brother just picked up an EVO and he want it as I'm planning on going with a T4 set-up. I still have my old HKS 4 inch mushroom laying around so I might use that for the time being until I find a decent 7-9 inch long 4 inch filter.
