Rated 5 out of 5 by from Excellent Performance Tiny Price Resurrecting a 1993 F150 Supercab with the 351 engine. Truck was sitting for 4 years. I must admit, I had my doubts about such a plain vanilla plug, but after reading the write-up on the "six litre tune-up" on the F150 and FullSizeBronco Forums, I went for it. Installed MSD coil, distributor cap and rotor and ford racing wires and these plugs. Even prior to discovering fuel pump was bad (reading of zero at the fuel rail, so barely a trickle of gas getting through) the engine would fire right up using these plugs. If they are that good with all the problems this truck has, they must really be delivering a good spark. Will update once repairs are all complete.
