what can a sri/cai possibly do to your engine in the long run?

Thanks Ya no GLC sedan for me. How many mazda's have you owned?

1989 B2200
1990 Protege GT

...in addition to the three cars in my sig I own right now. When I was a teenager, my brother always had 1982-ish 626 RWD's, which I'd love to see again sometime. My sister had a 1993 Protege SE, my mom drives a 2000 626. Unfortunately, my next car won't be a Mazda. I'm sick of driving economy cars (there's just too much crappy plastic inside new cars); I'll be getting an MB or BMW et al.
