glaze Posted January 17, 2015 Share Posted January 17, 2015 Hi Guys, I am buying some new spark plugs today and wanted to know what model NGK's I should be getting and what I should have them gapped at? Thanks heaps and enjoying tidying up my R;) Link to comment https://www.sau.com.au/forums/topic/452837-putting-in-new-spark-plugs-ngk-gap-to-what/ Share on other sites More sharing options...
GTR_JOEY Posted January 17, 2015 Share Posted January 17, 2015 Get the copper ones with a 7 heat rating What power level and boost you running? If unsure gap to 0.8 to be safe Link to comment https://www.sau.com.au/forums/topic/452837-putting-in-new-spark-plugs-ngk-gap-to-what/#findComment-7463120 Share on other sites More sharing options...
glaze Posted January 18, 2015 Author Share Posted January 18, 2015 315awkw at about 18-20psi I believe. Thx. Is there a model I should ask for or the guys at Repco/Autobarn will know?

jiffo Posted January 18, 2015 Share Posted January 18, 2015 Difficult to offer correct advice unless you supply full engine details. Generally speaking, you should run the max gap possible and for a stock engine with decent coil packs that's 1.1mm. Likewise heat range would be 5 or 6 for a standard engine. Once power is increased, you may find ageing coil packs can't keep up with the increased combustion pressures and the easy fix is to reduce plug gap. Wouldn't suggest less than 0.8mm. If it takes a really close plug gap to avoid blowing out the spark you should be looking to new coil packs. Heat range usually alters a range per 100hp increase over stock and it's pretty easy to have a 200hp increase. Cold starts could become an issue with very high heat range plugs. Make sure your IGN timing is correct while you're at it. 1 Link to comment https://www.sau.com.au/forums/topic/452837-putting-in-new-spark-plugs-ngk-gap-to-what/#findComment-7463148 Share on other sites More sharing options...
GTR_JOEY Posted January 18, 2015 Share Posted January 18, 2015 BCPR7ES -11 The 11 is 1.1mm regap to 0.8 NgK brand Link to comment https://www.sau.com.au/forums/topic/452837-putting-in-new-spark-plugs-ngk-gap-to-what/#findComment-7463149 Share on other sites More sharing options...

XKLABA Posted January 18, 2015 Share Posted January 18, 2015 If you get them without the -11 on the end they will be 0.8-0.9mm So BCPR7ES.

glaze Posted January 18, 2015 Author Share Posted January 18, 2015 I am fitting some Splitfire Coil Packs at the same time. So .08 is what I should go for? And thanks a lot guys!!

jiffo Posted January 18, 2015 Share Posted January 18, 2015 For that hp GTR-Joey is on the money, but with your new coil packs I'd go for 1.0mm and see how she performs. Check the shop actually sells you the BCPR plugs. Often they'll offer BKR which is the same plug but built to ISO standards and protrudes 2.5mm shorter. With them you need to give the spring conductor on the coil pack a bit of a tug to ensure it reaches the tip of the plug. Grab some nickel thread anti-seize and apply a match head dob to the thread of each plug. Tighten the plugs to the correct torque. Too loose and you'll see carbon up the threads of your old plugs. (the most common cause for stripping plug threads in alloy heads) Blow the valley area clean with compressed air before you start removing things. Remove/re-fit spark plugs one at a time. So easy to drop an item down an open plug hole and suddenly that 5-minute job becomes very expensive. 1 Link to comment https://www.sau.com.au/forums/topic/452837-putting-in-new-spark-plugs-ngk-gap-to-what/#findComment-7463180 Share on other sites More sharing options...
glaze Posted January 18, 2015 Author Share Posted January 18, 2015 Thx Boys. Luckily for me my mechanic friend will be doing the work, but will fill him in with all these tips. Also picked up a fuel filter, wondering how easy are they to change in the R32 GTR?

Time for a re location kit I think I use Z442 filter, it's smaller, thus easier to manoeuvre through the pipes and stuff.

pol1on1 Posted May 10, 2015 Share Posted May 10, 2015 I'm reading this topic and it's great but anti-seize Common! !!!! You got to think that if you putting that stuff on ya threads you start to isolate the plug from ground !! Your coil is powering the plug but can't discharge it properly so the it searching for ground ...... Now it will find ground eventually where you did not coat the thread with. Now it can be a possibility of it electrode erode ya head meaning stripping ya threads slowly. So not a good idea But if you really find the need to put some lubrication on it... use graphite powder. This stuff is highly conductive and it's a dry lubricant. Also do not use copper anti-seize coz it's reactive with alloys and normal nickel (silver ) is not good coz it's got lithium grease (non conducting) Just my 2c Jiffo I agree with your comment and great tips apart the Anti-seize Link to comment https://www.sau.com.au/forums/topic/452837-putting-in-new-spark-plugs-ngk-gap-to-what/#findComment-7531366 Share on other sites More sharing options...
