Just a general wondering as to what brand of intake system you guys are using on your turbo fc? Experience and any noticeable power gains from different brands?

 

those who never upgraded their intakes will generally say that stock is the best. My car never came with a stock system but i can tell you that it will make a difference.

K&N makes a FIPK kit for the S4 *thats what they call it, fuel injection performance kit* basically consists of a adapter and cone filter *their kit does not change the hose*, and they wont release a kit if it doesn't make a certain percentage gain over a stock setup*.

Theres not really any mass produced kits for our cars so alot of people go with a custom setup, basically anything you want.

 

If emissions legality isn't a concern, you'd be best off making your own. All you really need is a tube with a bend of 45º or so, a few appropriately sized couplers, and a high-quality air filter. The hard part is actually making it useful: https://www.rx7club.com/2nd-generation-specific-1986-1992-17/diy-cold-air-box-830116/

The tube can be usually be sourced from eBay 'cold air intakes' for various Hondas (3" 45º, cut to length yourself), or you could go to a supplier and buy it directly.

 

I like the custom intake, very nice, but no one has experience with a SARD, Blitz, Apexi, HKS etc? They do sell kits for the S5 TII. * Thanks for the link!

 

I probably wouldnt expect a big diffrence between performance intakes. You will feel one between the stock and aftermarket for sure though. Even with a drop in KnN mine boosted way faster and harder with an aftermarket set up.
