need for a complete tune up.. Can I do this myself? -

its a coil over plug set up. remove each coil pak and there is a plug under each one -
Answer 2
yes. rec. performance type coils as replacement. accel supercoils are good as well as more cost effective than OEM replacements. rec. e3 spark plugs as replacement however any premium type plug will suffice. rec. fuel system clean. ethanol treatment to 1 tank premium fuel. rec. upgrade conventional air filter to high flow design(K&N). rec. oil stabilizer treatment with next oil change. -
