best spark plugs for 1997 z28
 

since it doesnt feel like the engine is pulling enough when i get on it im sure its the spark plugs so with that in mind im wondering the best spark plugs out there i know delcos are good but also i heard ngk double platinums are good but why are the 14 a piece that like 102 bucks for plugs is it even worth it? it says that they give you "better gas mileage" is that some bs or whatsupp guys part numbers would help too thank you!!!!

unless you meant "87 z28" this is in the wrong section...I'd suggest not going cheap, especially if you're having issues.

try e3 plugs 5.99 a piece better gas mileage and power

Go with AC Delco or another stock equivalent honestly, probably your best bet. Did you try seafoaming the car also?

I myself seafomed my car and it didn't smoke as much as I thought it would put it through the brake booster vacuum line

BTW the more it smokes the more carbon it had built up it cleans it out pretty well good product

My neighbors called 911 when I sea foamed mine.
Good times trying to explain to a fire chief and police sergeant what I was doing.
