As I'm going down the FMIC route, I will need to get an induction kit etc.

Now looking at as many engine shots as I can, I notice that quite a few peeps go down the what looks like the K&N kit here, in the US from the ones I've seen its the Perrin kit and in the Hyper Revs book I have the Japanese tuners seem to opt for the Yellow/Green filtered HKS one.

What's the difference between them all? I would prefer the HKS green filter but I am open to change for the correct reason.

Thanks

Hybrid FMIC comes with an induction kit as part of the package, you will need to buy a cone filter though.

 

The RCM kit is good stuff.

 

Does this help ?

actually looking at the date it's a very old article, does anyone know of a more recent comparison ?

 

Good find!! looks like its an Apexi one for me then!!

Cheers for the input guys.

I opted for the APS 70 CAIK, with cold air feed. No problems and no restrictions, runs very well for this level.
