i have a non supercharged 95 boneville and what are the best spark plugs to go with? what type of ac delcos came from the factory? were they platinium? also what wires are good to go with? bosch? carol wires?

what plugs would u recommend to go with?
bosch?
champion?
ac delco?
autolite?
motorcraft?
denso?
ngk?

from the factory your bonneville came with the standard delco plugs, not the platnums AKA the plugs that sell for around 3 bucks for two. If you want the best get some expensive NGK'* or Delcos, stick with them two, Bosch is a no no for sure, we've had issues with those plugs in our cars. As far as wires goes, Delco OEMS are fine, but if you can get your hands on some Taylor plug wires, or MSD even, you would be good as gold.
hope this helped.

Autolites are a great plug, especially for the 3800. Intense Racing recommends them for our applications as well.

Autolites usually don't last as long, but they are really good in performance oriented applications.

I think the Series 2 comes with Delco Iridium'*. Those are what I got before I switched to NGK'*.
I'd say stick with the stock stuff, you know it wont do anything goofy.

Tell that to my plastic intake manifold and plastic/silicone lower intake gaskets, my transmission that had all kinds of issues before I replaced it at low mileage, and all the wonderful fit and finish issues GM has on these cars.

bosch plugs have problems on all gm cars from what i heard from a gm certified technician

I just installed NGKs in the 96 2 weeks ago and im really happy with them
I would recomend them, gap them at 55 and you should be good to go .

I love my NGK'*! I honestly and seriously noticed a slight gain in acceleration. Seriously! And the Delco plugs that were in there were still new looking but the gaps were a bit off which is the reason I think I felt the increase.

NGK TR-55 VPowers gapped at .055". That'* one heatrange colder than stock. NGK actually makes the AC Delco plugs.

Plug wires should be ok with ANY premium set.
