E3 Spark Plugs
I changed mine over A year ago with E3 spark plugs 3.99 each they are good for 100000 miles they say and I never had A problem so far, my original ones that came with car lasted till 116000 miles till I got A misfire code and changed them all. Also same performance as original ngks

Etc.
Some people like to upgrade to the NGK Iridiums LFR5AIX11
For a colder plug, just change the "5" in the part listing to a "6".
I've used the E3 plugs for 5 - 6 years in 3 different cars and they have been fine. My cars are daily drivers so I can't comment about how they would be in a modded engine. What the Professor experienced was somewhat common when E3 first came out and alienated a lot of people.
70,000 miles\ 7 years later i'm back and they still working, great plugs from my review. Getting same new ones today, not gonna wait 100k lol. Wonder if they really do give you 5 HP like someone here said they saw, either way great plugs.
