I'm going to do a complete tuneup on my 99 K3500 7.4L and was wondering what brand to go with. I'm going to use AC Delco double platinum plugs plus wires, cap, rotor and coil. My local auto parts store said their SMP ignition products were better than AC Delco (of course) but thought I'd ask as I'd like to use the most reliable and longest lasting parts.
I worked at a parts store while I was in College. People who work at parts stores (Besides myself, of course,
) are not always car guys/gals. Sales goals and strategies are pushed onto them and sometimes (Oreilly's) we would receive spifs (money on our check) for selling a particular item or brand during a period of time. They also pay barely above minimum wage. If you get lucky, you may find someone who actually works on cars and is knowledgeable... but those are few and rare, so ask the forum like you did!
I always say buy what your budget dictates, but be prepared for the consequences... If your vehicle is down, and you need a part get to work tomorrow and you can only afford the cheapest part, then obviously you get that part.
But, if you are not constrained by money or time and you want to get top quality stuff, ACDelco is a well known brand that has proven quality. Delphi is another...
