I debating on get just the K&N replacement filter for my IS 250 AWD or possibly getting a cold air intake. The one thing that worries me is that I live in Buffalo NY and its cold during winter will a CAI be ok during the winter would it damage my car any? (keep in mind the roads are covered in salt) If not what is a good intake for the money not worried about hp gains just looking for a decent sound and so called "improved gas mileage"!

 

intakes are useless unless your going boost or all motor mods. drop in is the best imo

 

Nobody makes a true cold air intake that's more "cold air" than the stock intake box.

If you want performance (and it won't be a noticable amount no matter WHAT intake you get, max of 5 hp) just spend $109 on the Joe Z intake.

If you want more sound at that point just drill an extra hole in the stock airbox so it looks like the F-sport box, that's free.

Anything else will cost more and provide hotter air.

 

All intakes suck. It's a design feature.

Some suck more than others. Those are usually the ones you want to buy.

 

So what would be the best drop in the K&N?

 

if you want it loud but not too loud, get the F-Sport
