Thanks for pointing out that thread. I just posted a response...

Thanks for all the positive feedback in this thread.

We probably make more intake part numbers for Subaru WRX/STI than everybody else combined. There are numerous SRI and CAI available in multiple configurations and in 65mm, 73mm, 83mm to match increasing power levels. We have also done 86mm and 89mm semi-custom intakes for people making more than 600whp using the stock ECU. We make CAI for stock-mount and rotated-mount turbos and for most FMIC. The larger MAFs tune easily and consistently. And it is all made to order or in small batches here in the Reno/Tahoe area.

Rules of thumb:
65mm <350whp
73mm <450whp
83mm <560whp
86mm <620whp

AEM DryFlow filters are a nice design and quick and easy to clean, so they are standard on many of our intakes. For some we still have to go with K&N due to size constraints, but an Amsoil dry filter is available. In my experience K&N filters work great and do not foul the MAF sensor when they are cleaned, oiled, and dried properly.

Selecting an intake for mod'd Subarus can be a little confusing, so don't hesitate to PM me, email sales@kstech.biz, or call - 775-250-7903 anytime from 7am-7pm PST. Especially if you have a unique or custom set-up.

Thanks again.
