Need tips on spark plus & fuel injector

Xsad · 01-08-2012, 12:56 PM

I was thinking to replace the spark plugs, like people said replace them every 3000 miles. How does HKS M-series spake plugs sound like, do I still to readjust the cap or they will come adjusted and ready to fit.
How about fuel injectors, do we really need to change those, do they even require high performance upgrade?
So please leave me some comments I'll be appreciate. Thanks.

-you don't need to change your fuel injectors when you change your spark plugs.

-just get the factory plugs but not from nissan. they are BOSCH heat range 8. they are just as effective if not better then the HKS and cheaper. It is also the colder plug out for this car so please don't ask for a colder spark plug, just advise.

-you should not have to change your plugs every 3k miles, thats more for your oil but it wont hurt.

-plugs should come pre-gapped for car specific

I hope I helped

The plugs are good up to 100k and come pre gapped most will opt to change them at 50k. I doubt you'll have that many miles so rule that out, also it's a PIA to get to the coil packs to get the plugs. The injectors are fine as they are, And you don't need to touch them unless you're upgrading to FI. Take the time to read your Service Guide this will give the basic maintenance recommendations.

That's way to often to change plugs. Even FI I wouldn't change but every 10 to 15K miles.

I concur with Triples. My brother is a mechanic and suggested the same path.

Agree! HKS M series is truly a trusted brand of spark plugs. I have read several reviews from satisfied customers and i believe in them. On the other hand, you can choose to replace the injectors as well as you think it should. post some pics here so that we can see how is it going.

Don't change the plugs that early... besides the fact that it is unwarranted, when you change plugs you always take small risks like cross threading the head, damaging a coil, or contaminating the block. I am not suggesting that an average person can't change a set of spark plugs but why add the possibility of a mixup for no added gain.

Changing plugs is easy. But a lot of people get skidish when you have to remove the throttle bodies to get to the back plugs.

I agree only took about an hour to do.
