Spark plug advice
I will soon be replacing the sparkplugs on my 94 Civic EX A/T. I came across DENSO Iridium sparkplugs. Do these really work and any ideas how much they cost? How much HP gain should I expect from these sparkplugs? The engine for my car is a D16Z6.
Thanks! |
RE: Spark plug advice
you probably wont see any hp gain over new regular plugs, they just should last a lil longer. in the best u might get better gas mileage. i would just stick with some new stock ngk plugs

much appreciated, thanks!

RE: Spark plug advice
It states clearly in the manual NOT to use iridium plugs.
NGK OEM replacements are where its at, hands down |
RE: Spark plug advice
it's also recommended to not replace the spark plugs for no reason, unless your current set is defected, save yourself the trouble. since you're working on an aluminum cylinder head, the spark plug threads can easily be stripped, so only change them when it's absolutely necessary. and unless you're running on 3 cylinders, you won't see a change in horsepower, unless they are fouled out.

why are iridium plugs bad? the manual tells you to do a lot of things that not even the dealer does, like use Thier MT fluid....dealers use 10w-30 motor oil....im sure the plugs cant hurt it....but yea, no real horespower gains, if you get your gap and TQ. settings right, you can see a tiny bit better gas milage...
Also cpl. rampage, i thought my manual gave a milage interval to change plugs and somthing else? maybey its a difference between 5-6th gens? oh wells |
