Is It Worth Replacing All Coil Packs?

[cannabiscorpse]

$590 for 6spitfire coilpacks and $1272 for originals from Nissan

Bought the spitfires and seem to have noticeably more acceleration now.

Can I expect my fuel economy to stay the same if I don't change my driving habits?

Same deal as me, although i bought the car with the coilpack missfire- so i cant really speak of what it went like with the oem coilpacks.

I wouldnt expect the fuel figure to go down too much though, unless of course it was missfiring massively.

Hi all, just thought i'd piggy back this thread instead of creating a new one

looking at replacing the coilpacks & spark plugs in my R34 n/a, would it be worth also replacing the coilpack harness also? happy to spend the extra if it will benefit the coils/igniton life in anyway - im just not mechanically minded

also Kudomotorsports have genuine nissan RB25DE NEO coilpacks for $450 (set of 6) - would it be worth it to pay the extra for Splitfires - is there any quality advantage over OEM parts?

also i was told that copper plugs perform better which can prolong the life of the coilpacks, any truth to this?
