Im trying to buy some better spark plugs for my 2.8l v6 firebird and my cousin told me E3 work great. Problem is when i went to E3's homepage my engine wasnt listed in the 86 year. Only 86 engines listed were 5.0 v8 and 2.5 L4. I DID however find a 2.8l for 1984 but that was a carburated engine, mines f/i. Does this E3 doesnt make any for my engine or did i miss something?

Also does any other 2.8 owners out there know a good spark plug for my car? Thx

 

ACDelco or NGK,anyhting more expensive is overkill IMO.

 

Go stock AC/Delco R42TS plugs. Your wallet and engine will thank you. Don't bother with platinum or any of that SplitFire/Bosch +2/+4 stuff as you're just throwing away money.

 

In my experience anything other than Delco's will not yield good results. Kind of like Motorcraft plugs with Fords. I have the same year car and only put Delco's in it. And for the love of God! dont put Chumps in!(Champion's)
