Heat Shield = $20, ebay
X-stream = $70, k&n direct
The new air filter makes a different, throatier sound than the original cone filter I had - since the top of the filter is open, I think the engine's breathing easier.
As for the heat shield, Not too big of a difference - I think the effects are mainly in my head - i.e., placebo
Just need to get my ur-ss crank pulley and i think i'll be happy.
I can feel the gains definitely from the x-stream filter, anyhow - whaddya guys think? open ended filter, heat shield - good or bad?
