hi guys has anyone changed their spark plugs yet?
i got 30 k on mine i dont know if its time to change them yet ,
thank u guys :))

 

As far as I know they are *supposed* to be good for 100K. I doubt I'll let mine go that long before changing but you should still be ok at 30K I think.

 

^thanks man Its because when I start my car it takes longer like I don't know what it' is

 

could be the battery...yeah, people usually don't change them for a while...definitely not at 30K.

 

Our stock plugs are rated for 100k? Wow, that's good to hear! Are they platinum or iridium or something? I generally thought between 15-30k for copper spark plugs for optimum efficiency.

 

hr is iridium

 

oh ok , so when do u guys think i should switch my spark plugs thank u )))))))))))0

 

i pulled one out @ 20k and it looked brand new.... so for "normal" people i would say never ?

 

oh ok cool how miles u got on ur carrito

 

i found some mega info

hellllllll ya

 

So, bumping thread back I realize but it's time for me to change my plugs. Do we have any for our engine that you all use?
Any pre-gapped ones?

 

dealership is your friend

 

Fawk! U mean to tell me they're the only ones that have spark plugs that are:
a) pre-gapped
b) made for our HR engine?

If so, insert 3 story cuss word here.

 

i think gtm sells hr spark plugs, but i think they're one step colder (which you won't need if you are at stock power levels)

genuine Nissan plugs might cost slightly more but at least you know they will last 100k miles.. and they made the engine so they might know a little more than aftermarket companies

 

Good point. Hate buyin from stealership but ah well. Apparently that's our only option for now.

 

GTM offers HKS M Series "HKS M-SERIES SUPER FIRE RACING SPARK PLUGS (HEAT RANGE 8)"

 

kinda off subject. but do you guys know when (what mileage) to clean the fuel injector? or is it better to replace them?

 

I want to know this as well as I'm at 60k on my HR
