i've always used NGK iridium in my R/A. but only a couple of manufacturers make the long-thread plugs that the 2.4 needs. but i'm fairly sure that your 2.0 will take the "standard" type plugs. Greddy and Denso make great plugs also...i have run both in my dodge dakota. there are plenty of choices out there...
I go with the NGK brand on my cars. Go with whatever metal that is recommended in the owners manual (which I think is iridium). And definitely don't buy into the pulstar crap that promises their plugs give you like an extra 10 mpg, 13 whp, a raise at your job, and multiple wives.
are the bosch plat 4 's any good? i used them in my other cars, never had issues. anyone know how they are on the lancer?
