In my past vehicles, I have put in SplitFire spark plugs and they performed well.
When I got my new 04 Dodge Neon I didn't change them because I didn't want to mess up breaking my engine in.
Well it is broken in now and I'm wondering if putting in SplitFire will make any difference. But I also don't want to void any engine warranty I have.
