Shifty6Speed Posted September 24, 2016 Posted September 24, 2016 Ok, so I've just ordered some NGK IX iridium plugs and they come in varying heat ranges 5 to 8. What does that mean? I've gone for heat range 6 is that going to be ok for my 06 pre uprev? Sent from my SM-G935F using Tapatalk Quote
ZEUS Posted September 24, 2016 Posted September 24, 2016 Why did you not just order the plugs recommended for your engine ? Loads of information on here about the correct spark plugs to buy or just ask a trader on here that will give you the answer? Quote
catman Posted September 24, 2016 Posted September 24, 2016 It's a REALLY bad idea to guess the heat range for your engine. Don't fit them until you've checked that they're the right ones! Tim 1 Quote
Tricky-Ricky Posted September 24, 2016 Posted September 24, 2016 (edited) You will need heat range 5 for the VQ engine, the numbers are the heat range of the plug, and should be kept at std range unless the engine is SC or TC. Edited September 24, 2016 by Tricky-Ricky Quote
Tricky-Ricky Posted September 24, 2016 Posted September 24, 2016 TC = turbocharged, but should have read SC/TC. 1 Quote
Shifty6Speed Posted September 25, 2016 Author Posted September 25, 2016 Ok guys. Thanks for the answers. I'll edit my basket. Sent from my SM-G935F using Tapatalk Quote
Lewis_UK Posted September 25, 2016 Posted September 25, 2016 (edited) This is what I'm using: NGK 6240 Laser Platinum: PLFR5A-11 No Turbo or Supercharger. Edited September 25, 2016 by Lewis_UK Quote
Shifty6Speed Posted September 25, 2016 Author Posted September 25, 2016 Yep. I'm N/A and only engine mod which will soon be fitted is the titanium zorst system. I'm trying to pin down a decent plenum spacer kit ready for the uprev map. Sent from my SM-G935F using Tapatalk Quote
