Well when it pulls back timing it effectively pulls out power.So when you have a colder plug you have less of a chance to run into the knock sensors and keep your timing and power where they belong. I have personally seen 7-10 RWHP on a dyno by simply switching from new factory heat range plugs to a colder plug. I get the AWSFA-12C plugs which are 2 heat ranges colder for 1.67 a plug |

This is done to improve spark exposure and flame front for better and more complete combustion. Some call it the nitrous mod. |

Bryan, how do you think I came to the conclusion that the 764's worked best? |

BTW what chris said about using colder plugs I have personally found to be true. My car would ping w/ 764s but I put in the AWSF-22Cs and it stopped pinging, and seemed to pull harder.

I don't have any mileage on the plugs, but I don't mind changing them. Maybe I can do a Tazzo run before and after and compare. |

Champion makes plugs for NGK as well and I could be wrong but I think Accel also has some plugs by Champion.
Edelbrock has joined with Champion because they feel they supply the correct and best performing spark plugs for all applications. I know Champion sold some crap for years but they are past that all and now produce some of the best plugs and wires around I also understand Champion produces Volvos plug wires. |

The matierials used were of higher quality, and would be less prone to causing preigntion. reason for this is champion uses copper cored ground electrodes, and dissapates heat alot better than any other. if you want proof, take a champion plug, and any other brand, hold them both to a torch, and watch wich one will glow hotter, and stay red longer. definately not the champion.

I run Autolites ONLY. I have had bad luck with Champion, Bosch, and AC. I've never had a problem with Autolites, and 2 days ago, I installed Autolites in my Continental, replacing Champions, (which looked like s***), that the previous owner installed.Everyone has their opinion, but my 2 cents is, go Autolite.I use them in my cars, and I recommend them to everyone I do tune-ups for.Noone has complained yet.

Try reading some of the spark plug manafacturers catalogues, and do some technical reading, find and learn to recognize spark plug conditions from a color pictorial demonstration chart. bet it takes you all of two hours to become pretty expert. Spark plugs are a very simple device, by the way I put three 20% gas saviong devices on my car two that improve performance 45% and then one more gas saver that does 48%. I can now pass anything on the road, the only trouble that I have to deal with is that I have to stop pretty often to let some gas out, cause all the gas saving devices I put on have been making my gas tank overflow from saving so much, the good part is that I am making extra money selling the gas that I have to drain off. What a great way to solve the worlds energy crisis, and create a new petrohydrocarbon source. thats all folks. Whats new?. BTW I like autolite plugs, great price, I use them as often as i can, but some of the other plug manuf. have half range as compared and when doing a fine temp match or fixing a particular cyl problem I do cross-brand, and sometime I use the matching brand for name sake of being oem.
