Lukey. 381 Posted March 26, 2011 Report Share Posted March 26, 2011 http://www.mister-solutions.co.uk/bkr5e-ngk-spark-plug-116-p.asp get these if you arent bothered changin them every 20k instead of every 40k. They are single instead of dual contact so if you get these get a feeler gauge couple of quid and gap them to 0.8mmBKR5EUP are 40k change original equipment replacement for an OBD2 VR6BKR5EU are OE for OBD1Just use the top for standard engine, supercharged you may want to go 1 or 2 cooler, which is the same BKR^E but 6 or 7, the higher the number the cooler the plug and with a 0.6mm gap Link to post Share on other sites

Lukey. 381 Posted March 27, 2011 Report Share Posted March 27, 2011 the general rule is for every 10psi run 1 range cooler Link to post Share on other sites
ian_GTI 0 Posted March 27, 2011 Author Report Share Posted March 27, 2011 I'm running a stage 2 vf charger but haven't fitted a boost gauge yet so I'm not 100% on what boost it's putting out Link to post Share on other sites
Lukey. 381 Posted March 27, 2011 Report Share Posted March 27, 2011 google seems to say that a stage 2 is about 8psi.the proper test you need to do, assuming that your remap is a good one that isnt too rich or too lean, is to get a set of 6 and 7.Run the 7 heat and if it runs fine leave them in for a couple of hundred miles then take one out and have a look at it, if it looks a dusty grey its bang on and you should leave the 7 range in. Black carbon buildup (wet or dry) means its too cool and the hotter 6 would be better, swap them for the 6 heat and in another 200 miles pull one out and check again, if its still black go to the 5 range, which it isnt going to be, but the principle carries on.Then you know exactly what heat range your car runs best on.
