Want to find out if anyone change extractor 421 experience CEL problem for MAzda 3 auto- can share or how to prevent CEL as this is the common problem. i am thinking of changing as i do not wan to spend time solving the CEL.
ive heard of supercharging and turbocharging an engine but this is new.
i couldn help but to think that this is ultimate street engine upgrade rather than turbo or supercharge since it peaks out the power of a stock engine in 0 - 4500rpm
do we have this in malaysia??
