Spark plugs

Recommended Posts

I have Supra TT GZ and I have recently bought these spark plugs for it based on advice from some of the members here ... http://www.myparts.co.uk/bkr6eix-iridium-spark-plugs-free-delivery-p-149.html ...I bought these off the same trader on eBay (And at the same price). I hope this helps :)

 

Bkr-6 is a hot heat range ok for standard cars but not bpu supra's, you need a NGK heat range 7 or in denso IK 22;), if your car is standard then NGK 6 or Denso IK 20 hope this helps

I use ngk bkr7's on about 1.0-1.1bar gapped to 0.8mm with no problems. Copper plugs are fine, just change them more often. iridium plugs are nice but are a bit pricey and really who is going to leave the same plugs in a bpu supra for 20,000 miles anyway? Apart from a narrower electrode I dont see the need for them (i'm someone will be around soon to correct me!:))
