Yeah I've actually seen one dyno test where a stock Camaro SS that gained about 8 hp on a K&N panel filter. I think people are really downplaying the drop-in HF filters.
Yeah same here. I actually found a few minimalistic wind deflectors:
Verus
Autotecknic
The only problem here is they don't look like they belong because of their plain texture (vs. gloss). Also, that Verus one is made for GR86, so not sure if that will work.
Was there a break-in instruction included? My instruction said to run the engine for 10 minutes after the install, followed by revving the engine to 2500 RPM for 2 minutes, and go easy for the first 5 miles after the install. I hope I don't get the CEL, but just wanted to make sure there was...
