Alright, definitely not the decision I would make but hell it's your car.

 

Oh no, not another plug thread here we go again Well, the guru's will tell you, and it has been my experience too, that regular cheapo replacement plugs are all you need, they work fine and you don't get any kind of gain from plugs, wires just make it look nice and the NGK's are the most reasonably priced upgrade for wire that basicly just look pretty. I have had magnacore and recently went back to stock and I could'nt tell the difference, just looks. Do a search, there are several threads on this exact topic with links to the Mitsu recomended replacment plugs, go with one of those and save your money.
