    I never use anything else.

    Don't be fooled by all the hype of fancy materials like iridium and platinum. They are "long life" gimmicks to try and get people to spend more money. I've removed these so called 100k mile plugs from vehicles at 40k miles and they were junk. The center electrodes were worn down to crusty little nubs. The reality is that plugs are dispensable and there is no reason to wait 8-10 years to change them. I just put these Autolites in our recently purchased 07 Tahoe (along with new wires of course) and it made such a big difference that even my wife could tell it had more power. If you can truly feel a power difference in a vehicle it's got to be at least a true 20+ horse power.

    Anyway, I've used the standard Autolite copper resistor plugs on all my vehicles for nearly 15 years now and have never been disappointed; vehicles like my 06 GMC sierra, two 2007 tahoes, 05 Cadillac CTS-V (mods like exhaust and Camshaft), 96 Camaro SS with mods like a Cam, rocker arms, supercharger, methanol injection, etc.

    My advice? Use these plugs and change them along with the wires (wires may actually need to be changed more often than the plugs) every 30k miles and save money while also having a vehicle that runs better. The wires are really a non-issue if you get some with a lifetime warranty. If they are free, why not change them often to keep your vehicle running strong and getting better fuel mileage???

    Pros: affordable, THEY WORK, relialble

    Cons: None
