How often do you guys swap NGK Iridium plugs? I'm running the NGK 7's. The car has been in winter storage. I was planning a plug change but was surprised I only put 2,200 miles on the car going to shows last season.
Are modded guys running tr7 or tr7ix?
What gap?
Yep...Depends on boost. 19+ boost TR7.
Recommended plugs are NGK TR7-IX (Iridium plug) and Motorcraft SP-471 / AGSF12FM1 (Platinum plug).Are modded guys running tr7 or tr7ix?What gap?
TR7IX is supposedly a better plug for quality idle and part throttle drivability and less random missfire codes.Are modded guys running tr7 or tr7ix?
What gap?
You absolutely do not need to be changing plugs often at all. Honestly even 30-40K is overkill.
Now that being said in my big power cars, I try to change them yearly because I run the snot out of the car and usually run additives. But to be blatantly honest it is a complete overkill and waste of money, esp on Iridium plugs
Who sent you the plugs Chancey?I am a fan of the TR7ix’s as most everyone is for our cars. But when I bought and installed my upper pulley, intake, tune and 69mm throttle set up, they sent me the NGK BR7EF plugs with the kit. I put them in just to give em’ a try. They have ran just as good for the 2,500 miles I’ve put on them. I am still gonna replace them with the TR7ix’s when I swap them.
Depends on the plug. I would never recommend running a TR6 or BR7 30k-40k. 10k miles maybe 20k at most.
what do you really think is going to happen to a plug still being used at 1/4 of its recommended lifespan?
You have never ran those plugs on a modded terminator or Gt500 for those miles. They start miss firing. Rough idle ect. Your more then welcome to try it on your own so you can actually experience those issues with those plugs.
