Tonight I did a quick run in an industrial park and had a problem. I back fired at the top of third. Damn my car is slow. I only got to about 91mph in that quick run. The back fire, is that from a bad spark plug??? DOes anyone have any ideas. I am planning on getting a 100shot of wet nitrous by the end of winter and want to get a little spark for the car. I plan on installing MSD Dis-4 ignition, Ford Racing 9mm wires, etc. What kind of plug would be good for the nitrous and daily driving??? Any other ideas for the the electrical system in the car or anything that I should look out for as a problem from a quick backfire??? Thanks!!!!

with their kit you can open the gap on your plugs and get way more spark. also you have to use 10mm plug wires.

Have you washed the engine lately, mine back fired once after washing it?

No I havent washed my car lately and unfortunately.

What spark plugs would anyone recommend if I am gonna spray it early next year. Forced induction may come into the picture but it will not be for a good while so it is little worry. Thanks

NGK irridium IX spark plugs. Run about 7 bucks a plug but work wonderfully.

bosch

No. Avoid bosch. They are great plugs...for imports. They don't seem to great on domestics. I've heard so many complaints from +4s and +2s it's not even funny.

if you plan on going fi....autolite or ngk r ....end of story try just cleaning/replacing cap/rotor first. then wires (look under the hood at night and look for arcing), coil, etc.

I actually was thinkin of going with any of the three mentioned. If I am goin FI or nitrous but still daily driven should I go with slightly colder plugs or what??? Srry but I am only marginally knowledgeable about different spark plugs.
