What are some good hardware vendors, price and service? I have been looking at some and it looks like some sell the same products but the prices vary or similar products (different brands) that I am not familiar with. I am looking at hitches, bull bars, tonnaeu covers, spark plugs and wiring, etc. Just looking for good prices and service for good products.

At what mileage do you change plugs? What is a good plug upgrade? 4.6 L with no mods. I have been looking at those E3s but are they too long? And is that design better than the standard gaped plug?

Just put in the stock plugs if you're not blown or NOS.
