This thread is in honor of Rizz, if you don't understand, read through the past few threads throughout all the forums. Anyway, spark plugs. How many have changed them so far? You're supposed to do them every 60K mi....5K mi is ok too...but I would guess overkill (*cough*Zwrecker*cough*). It's a pain in the butt the first time to get to all the coil packs and get them out. That balance bar is IN THE WAY! Make sure you have a long enough extensian as well, and an elbow on the socket is helpful as well so you can get the correct angle on it. Number 6 is the hardest one to get to by far. I found it easier on some cylinders to tkae the coil pack out as far as I could before taking off the plug wire connectors. Also, for those who haven't done it (basically who this is for) make sure to replace the old plug with the new one immediately as you don't want debris falling into the cylinders. Alright...post away!

i know i know... i change them every other oil change, just so i know i get a good spark every time. what can i say i love my Z maybe a little too much....last spark plug change was before i lost my lisence so....roughly 5 months and 2 weeks, and i put the expensive spark plugs in so i am not gonna be changing them for at least 15k...so there you happy

This would have helped like a 2 months ago when I first acquired my new 300. But alas, i got throu it, but good tech thing pal. I took the balance bar off. And I had a friend do the cils while i did the plugs so it took like 20 minutes.

So, in your honest opinions, what are the best sparl plugs for the 'Z'?

emo236

NGK 6bs or 7bs depending on how much you're modded.

NISMO LMR

replacing spark plugs is no big deal... Now tearing the upper half of your engine apart, now THATS a headache, I KNOW! Haha, but are stock good, because I was considering HKS? Worth the extra moola? Peace foo's

What about Bosch Platinum?

NISMO LMR

But if I get HKS ones, I can put an HKS decal on the side of my car! Thats an easy 10-15hp more for each decal right???? haha . Which are better though??? Peace foo's

emo236

I've always been advised to use NGK. This is from numerous Z specializing mechanics(well, 3) and numerous buddies and knowledgeable Z owners. I don't know baout the HKS ones, but I've heard Bosch's are crap...don't know if that's true...that's what was in my car when I pulled them out.

You mean you don't have another comparison article for us? This is now becoming an opinion poll.

emo236

I always thought that Bosch made a good product. I didn't say anything earlier because I didn't want to sound like an ***. Are there any problems with Bosch O2 sensors, or does my previous theory still hold true.

emo236

What am I, your research slave...you go research on this and report back to us on this...if you please. If not, I'll probably be a sucker and do it for you in a few days.

91zxtt

I'm patient. I can wait.

Z_WRECKER

hahahaha......you guys crack me up... I AM SO TIRED....I NEED SLEEP

emo236

This is for Rizz.
They say you should go at least one step colder than stock if you're stage three or above, are the standard bosch platinum a step colder or do they come a step colder?

Z_WRECKER

i dunno man... and i dunno how do you check something like that....like temp resistance or something?

91zxtt

Hmmmm. No clue.

emo236

For instance, the NGKs come in 5B's, 6B's and 7B's. 7s are the coldest and 5s are stock. Here, look at this link.

My boss offered me all 6 NGK spark plugs for 50$... Good deal? He said theyre the best they make, he's used them in all of his Skyline projects. Peace foo's

Z_WRECKER

thats a good deal, bc NGK are pretty expensive and thanx for the number info. i always wondered what it was

emo236

I got them for $45 b/c I have a hook up at the dealer, but $50 not bad either.

NISMO LMR

Well I checked, they retial for 16.95 a peice at any store basically. So 50$ all the way around aint too bad, peace foo's
