I know several people have CAI and there are several brands to choose from. Most of the intakes have a 4" opening. If your filter needs to be replaced, can you use ANY filter that has a 4" diameter to fit the intake pipe? I also understand that some Air Filter allow more Air Flow. Will this affect your tune in any way? I had mine dyno tuned and if I change my filter will it require me to recheck the A\F ratios and so on?

 

I was wondering the same thing.

 

I know, but nobody is answering????

 

I'd said you'd be OK... regardless. Why not just get the replacement filter through whomever you purchased the CAI from if this is a concern?

 

Amsoil makes replacement filters fitting most CAI setups. They supposedly filter more dirt and flow the same or better than the standard oiled gauze setups. Plus they are a dry filter that you can clean with just a vacuum or compressed air to blow them out. No oil to worry about clogging your MAF. http://www.amsoil.com/StoreFront/eaau.aspx

 

Just curious if the different filter will affect the tune. I doubt it, was just curious. The one that came with the CAI is a red one and I would like to get a blue one to match the car color.

 

Blue would definitely require a new tune...LOL

But seriously, I am considering a Amsoil filter once my S&B gets dirty again.

 

If blue colored filter oil is you're preference ? look into Steeda as they sell it exclusively for their CAI filters..
