vxr8 plugs

[kaw]

best plugs for the r8 and does anyone know the gap size,just looked at mine, gap looks way to big but can,t find my feeler gauges

[ringram]

1.1mm aka 0.055 IIRC
Heatrange 5 for stock, 6 for performance & light FI and 7 for madness.

[kaw]

mine look much bigger than that and are ac delco two numbers 12571164 and 41-985 do you know the ngk part number mate and who does them

[ringram]

bpr5es or 5ef from memory. Halfords do them in copper cheaply.
You can also get iridium etc, but they cost mega

Ok just phones NGK with the 41-985 part number and they came back with ITR6F13 (4477) they are in stock and u should pay around Five pounds a plug. Theses plugs are iridium so will last compared to copper.

Hope this help

SI

I think that is nearly cheaper than over here! I bought some a few weeks ago. Thought they might have gone down a little at least but alas no!
NGK are even more. The 6 litre VE can use iridium NGK TR5IX so not sure if that applies to VE LS2 and LS3, looking at the US sites it does.

Must admit im not a fan of iridium plugs, the reason its used is because its very hard so lasts a long time. Trouble is ive seen a few instances of the tips dropping off the plugs (which is fairly common) & as a rule because its so hard it tends to do a lot of damage on its way out where a standard plug if far less likly to do damage.

Must admit its mainly high boost turbocharged engines ive seen it on so maybe its helped by the high boost, 1 thing that is intresting is that it seems to be Denso plugs tht suffer more than any others ??

Also there are better conducters than Iridium to be honest Platinum & silver based plugs are better imho

Used to see this on the Denso Iridiums (IK's) but never had a problem with the NGK's. Denso now do a "tougher" Iridium.
