i know some of you will discourage me from doing this, but im going to do it. i just don't know what plugs to use. sparkplugs.com says that i can use Champion, NGK and Denso. i HATE Champion with a passion, part of why i want to change my plugs. i wanted to run Denso because i have heard all good things and that they are supposed to be some of the best plugs on the market. I have heard alot of good about NGK also, but i have never used them. the Denso plugs are hard to get and will take me a couple weeks to get them. i found a cross reference for the NGK. i work for a Mitsubishi dealership and we keep the NGK plugs in stock. if i went with the NGK, it will cost me about $20 more to run those. if you had the choice, would you pay the extra and go with the NGK?
