What spark plug is the best for the US Lancer I looked in the owner's manual and found NGK, DENSO,CHAMPION and also searched autozone.com and found BOSCH-PLATINUM_2. Which one is the best fokr the us lancer i searched but did not find a thing can you smart people help me out.

 

stick to jap. brands i run ngk on my ///RRM turbo lancer oz due to the advise of Rob @ www.roadracemotorsports.com

 

one more thing i forgot your car has NGK in it already

 

NGK vs. DENSO which is better

 

You're really not going to notice a difference either way. Honestly...flip a coin or just buy what's cheaper/more expensive/helps you sleep at night.

i'd go with denso iridiums, they are good when pulling hard at high rpm's...obiviously they don't last as long as stock, but the performance gains is a teenie tiny bit noticable..your gas mileage improves too..BUT BE WARNED!!! DO NOT GET BOSCH PLATINUM +4...the 4G93 engine cannot, will not, doesn't like it. although it fits...for some reason, it responds horribly to it. i was racing a friend one night at the lil ****s blew out on me...the dealer told me not to get them either..so go with Denso iridiums...
