Anyone running a Bosch plug 4479

Got a few on liquidation? They look neat, but are they all show and no go?

I am running a set in my 88 5th.
I got them from Rock Auto at a good price. They run great for me. I installed them when I did a complete tune up, plugs, wires, dist cap, rotor and new coil. Starts fast and runs great.

thanks man. I have been running Champions and figured after years of these advertized so call rapid fire plugs with multi tips & and newer designs, I'd give it a try.

I ran bosch multi tip plugs in my 83 D150 for 2 years with no problem.But also didnt make any difference in engine performance.Installed champion plugs the final year I had the truck.Gas mileage and performance never changed.
