![]() ![]() Guess what.the original OE AC DELCOS were BOSCH's. Both of us had to change plugs before 50k miles due to misfires. I just have good luck with the Autolites and they were actually better than the OE Delcos in both my and my dad's 2008 CTS's with the DI 3.6. I have to admit that you are absolutely right and I know this and agree. At $3 for iridiums AcDelcos I'm tempted to buy a set although I don't need really need plugs. $2 off iridium and you can get them for as low as $5. There's a mail-in rebate on ACDelco plugs. I always like to use OE parts when the price is reasonable. Both fit and work but only the first one is OE. It's not too different from choosing an ACDelco classic oil filter vs a FRAM. GM could've used Autolites or some other at probably lower cost but chose the NGK design. Corona stain Corona stain is a light brown or tan discoloration on the outside of the ceramic insulator above the metal shell/hex. Anti-seize compound can act as a lubricant altering torque. NGK tech support has received a number of tech calls from installers who have over-tightened spark plugs because of the use of anti-seize. NGK spark plugs are installed at the factory dry, without the use of anti-seize. NGK spark plugs are installed at the factory dry, without lubrication or anti-seize. The coating also acts as a release agent during spark plug removal. The coating also acts as a release agent during spark plug removal. The nickel coating on most modern spark plugs provides added protection from seizing in aluminum cylinder heads and has made anti-seize less important in spark plug installations. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. It is completely unnecessary and can be detrimental. Anti-seize NGK spark plugs feature trivalent plating. You know it not just fits exactly right but is also the exact same heat range and durability has been verified. Do not use anti-seize or lubricant on NGK spark plugs. But the way I look at it is I'd rather have the OE plug (or in this case, also the NGK) for my own vehicle or where possible. Anti-seize compound can act as a lubricant altering torque values up to 20 percent, increasing the risk of spark plug thread breakage. I put a light coat on all spark plug threads, and any bolt that I feel I may want or need to remove again within the life of the car.I don't think there's anything wrong with Autolite or Champion plugs.

NGK tech support has received a number of tech calls from installers who have over-tightened spark plugs because of the use of anti-seize. Be a real man and get that boraxo and lava soap working, and if Dawn removes grease from the dishes…it’ll do wonders for your greasy hair. Hell your grandma had one soap for everything, now they are advertizing body soap for men. A soap for your hair and a soap for your back and a soap for your face. Pretty soon someone will come up with bulb grease and you’ll have one more thing to buy. I never knew it existed until a few years ago and I figure if White grease was good enough for the 40 years before that…it was good enough now. I’ve never had a problem with the grease NOT allowing current to pass thru.ĭi-electric grease is all fine and good, but I only use it on rotors, caps and plug wires. I would only goop the stuff on the plugs if you have a Diesel. The grease only seals the plug from the elements including oxygen that would promote corrosion. Bulbs, electrical connectors, battery posts, trailer light plugs…everything except rotors and caps. I have always done like he taught me and used a little white grease on any bulb outside the cab and exposed to the elements. He’ll start moving tools to other drawers on me!!!. NGK spark plugs should be installed DRY, WITHOUT anti-seize. ![]() Old habits die hard and I don’t want my dear old dads spirit comming back to haunt me ![]()
