Spark Plugs

Eav10xB · 09-25-2008, 12:00 AM

To be honest i didn't like the NGK Iridiums. In my opinion they aren't that great. The next time I change my plugs I will try the bosche iridiums with 4 electrodes and see how that is.

i just switched to NGK V-power....no need for iridiums for me.... and gapped at .32

AirecK · 09-25-2008, 03:32 AM

only difference i noticed was i was getting up the hills much easier..not struggling at all...
but i also changed the oil , filter, and finally put on that new ingen airfilter cone...
but yeah ... and were only $8+ for the 4 plugs..

yeah I noticed a HUGE difference when going from dino oil to Mobil 1. sooo much of a smoother idle.

Seriously guys... just get the stock replacement. NGK brand. we have a 100 HP box and it doesnt ROCK. we dont have high compression, we dont have high HP, and most of us arent turboed, no need for colder plugs.

Platinum plugs and iridium plugs should come pregapped for your specific tolerances... the electrode is fragile and if you chip the plat or irid coating on it the plug is no good.

tell that to NGK... They said Pre-Gapped i checked the gap and they were at .52 when they should have been, i believe it was like .30 something. Don't remember i just remember it being a biznatch to get back to the required gapping.

I am running Denso Iridiums SK16R11 factory replacement from a 2000 Echo motor. Definately an improvement over factory plugs

Addicted2theBOX · 12-01-2008, 04:11 PM

NGK all the way.

So which one is the stock replacement for the NGK brand?

I have over 75,000 miles on the Denso Iridium's and they work great

question -- i bought the cheap

ngk v power plugs and checked the gap and it was set at like .29 would it make a difference if i change the gap and what gap setting should i change it too

thanks

Just FYI, I think it was already mentioned by someone earlier, but you should always check the gap on new plugs. Just because they say they are pre-gapped, doesn't mean that they are correct. It's been my experience to have at least 1 out of 4 plugs to be out of spec straight out of the box.

viola000 · 05-18-2009, 09:28 PM

NGK Iridium fan here also...

bieniman · 05-22-2009, 11:53 PM

So how much do they differ in price compared to performance?

what gap you running these at?

chrisdesil · 05-23-2009, 08:41 AM

Just about to reach my 30k mark. Any suggestions for a turbo'ed xb? I should probably be running a cooler plug.

USDM xB uses A .032 gap, not a .32. I myself use OEM Toyota Denso Iridiums (Toyota P/N 90080-91184 & Denso P/N SK16R11) which are gapped at .044 I did this because the JDM xB uses this gap, thats the Gap that the motor was originally designed for, I tried it out to see if it helps with my rough idle and it did, and I'm happy with it.

Bosch has caused a lot of Japanese cars I know of personally to fail smog here in So. Cal. when equipped with Bosch parts, So I do not use Bosch parts in Japanese cars. I only use Denso or NGK. Also, having more than one ground electrode is useless since electricity follows the path of least resistance, those 3 extra ground electrodes are just a marketing gimmick.
