Nobody has a larger selection of parts AND the pricing is (usually) cheaper than any other retailer, including Amazon. As a Ford F-350 owner, RockAuto usually has the Motorcraft version of the part you are buying. Bought Motorcraft spark plugs priced 25% cheaper than my local Ford dealer.

If you enjoy wasting money, buy your parts at AutoZone. If you prefer brand name parts at lower prices, buy at RockAuto.
