The one that is cheapest.
Really..on little 4 cylinders intakes just increase throttle response and make the engine sound cool. My advice is to spend as little as possible. I always laugh at people spending hundreds of pounds on intakes.
Thinking about getting one for my Focus. Take I should just go for something like a K+N?
I tohught a lot of them smooth the power delivery rather than add any realy BHP gain?
I think k&n induction kits are pretty much the worst on the market.
I want to fit a CAI on the skoda but with all the train we're having I don't really want water to get into the intake!!!

Based on the above article, the only filter i would ever trust would be the Apexi, I ripped out the K+N panel from my honda the moment i go it, and replaced it with a standard filter.
Based on...........?
based on pretty much every induction kit test I've ever read and the opinion of everyone I know who has owned one and replaced it with something good
And based on David Vizards testing it was one of the best performing filters for use on Baja buggies that see a lot of dust.
standard airbox, panel filter, and if possible cold air feed![]()
