Spark Plugs (Page 2/2) theogre JUL 16, 05:50 PM ⚠️ Warning: Anti-seize only helps so much and worse many install plugs and other things way too tight because Anti-seize act as Oil/Grease tightening whatever. Like most Heat Sink "Grease" the oil is just a carrier to flow out over what used for and dries out. If you over-torque @ install, will be even harder to remove. quote Originally posted by olejoedad: I will disagree, use the AC Delco copper plugs. Believe that all you like... Fiero V6 Front Plugs are very well known for rusting basic shells very fast. Worse if driven w/ road salt or ocean spray. 4 cyl plugs can have Same problem. Worse for 1 and 2 cyl where Polluted Water gets thru engine bay vent even if have rubber edge "seal" for the vents and deck lid along rear glass. This is what I replace this year and car driven < 1000 mile per year. Plugs ordered online and while have same PN, 1 is old stock with "cheap shell" vs other 3 coated shells and #1 still rusted big after ~ 5 years. Even 3 & 4 had some rust thru the coating at the taper. ("Double Platinum" APP666 because has DIS. You Do Not Need this for HEI systems.) Cheap shells are part of why "basic" plugs have 0 days to 3 year warranty. Warranty Does Not cover Rusting of the shell in 1 to 2 years. Even if the "nut" is ok, rust makes stress points and can break the shell if have problem getting them out. More so if over-torque @ install for any reason. What you Don't want is Gimmick Plugs like multiple grounds or worse. For many users just eats money doing nothing. GM DIS and others outright Hates them and can burn out the Coils when the plugs go bad. Even Bosh Platinum w/ thin electrodes causes many problems in Waste Spark DIS in GM and some others.

They're quite popular. I used to use standard copper core NGK plugs in everything I drove... until I got a smokin' deal on a lot of Denso plugs (for the 2.5 and 2.8) years ago in a close out sale. And yes, I made sure these plugs were favorably reviewed before I bought them all. Still use NGK plugs in my JDM Subie. Mark_j JUL 16, 06:52 PM I guess I've never lived in a place where I had to think of rust issues like that even here in the NW. Anyway here's my go to for most applications. Autolite, AC standard copper core for most domestic engines (really depends on price/avail at time of purchase) NGK standard copper core for most foreign applications. Anything else is either a gimmick or not really suited for the majority of the older engines I run. The only real exception I had was a Honda 750 interceptor that LOVED Champion spark plugs. Don't know why. It ran ok on NGK and Denso plugs but something about the Champions really brought out its performance. (and no it wasn't because I had a champion sticker on the cowling). My 2 cents, YMMV greenturnedblue JUL 16, 06:58 PM worst case scenario, this happens:
