Now I've been doing alot of research and looks like once my brake-in is finish I'd go with the HPS Tube and drop in.
Now as far as Drop-in HKS, K&N, and Now I learned about M7....
HKS is a no brain-er,
but K&N vs M7? anyone try out this company? Products are designed and manufactured from Japan.
And surprisingly Cheaper than KN drop in... Hm
M7WorldShop
Opinions?
