NGK ltr7ix-11 plugs for whipple

[Roh92cp]

In preparation for my new motor I wondering if I should reuse my plugs that came with the Whipple's kit. The plugs have about 5k on them when they were pulled from my failed motor from OPG disaster they still look good. How long do these plugs last? Street car only.

That is a great question ...Glad you asked because I would like to know also ..

On my turbo bikes they get changed almost every race , 18 PSI with q16 fuel ... N/A Street bikes that sees a lot of track time and street time about 9 to 10k miles before it will start dropping holes .. NGKs seem to hold up the best for either boost, spray or N/A ..

Why risk it. Just get new ones.

For the cost, why worry about the if? Just get new ones.

Right I get it since I'll be right there, but how long should we be running these plugs on a street car. Should we be getting 5k, 10k or more out of these?

I wouldn't be afraid of using them. Plugs had nothing to do with low oil pressure.

I think I remember Whipple saying 30k
