rec. performance coils as replacement. accel's are pretty good as well as more cost effective than OEM replacement. you can clean throttle body also. spark plugs rec. replacement 50,000 miles. rec. premium type(e3) as replacement.
rec. fuel system clean. ethanol treatment to 1 tank premium. ethanol blend in fuel causes build up in fuel system, combustion chambers, exhaust system and causes increased wear to spark plugs.
