3.3TT HKS M45iL Plugs after 1 yr

After 1 yr and ~10,000 miles

HKS M45iL

I could easily continue to run these for another year before changing them, but I already pulled 3 so I might as well change them. Gaps were still tight between .022-.024. It only took 57 minutes from start to finish to swap them.

I’ll be sticking with the same plugs. I’ll check back after 2 years.

Thanks! Will probably order these once I hit 10-15K on my Densos..

Edit: actually, will probably re-gap the OEM plugs and drive those for 10-15K before that..

They better last 2 years for that price. Denso's could last 1 - 1 1/2 years on map2.

I run Map 7 daily. I haven’t seen Map 2 since the week after the JB4 went in over a yr ago.

Given the reported issues with some of the Denso plugs, I’m happy with my purchase.

YMMV

Sure, but you probably also have more mods than most..

That I don't know. But before adding meth and before I had an exhaust and intercooler, I ran Map 5 daily. So I wouldn't attribute spark plug longevity to the mods on the car.

Was that the old map 5 that's now map 3? I'm running current map 3 with an E30 mix.. Map 7 is a whole other ball of wax

I think so. Whatever the E30 map is/was.

These are my plugs . I am .028 because stock boost and i am happy with how those look. The stock ones after a year and i half looked trash and had burnt ceramic all around.

Missfires with stock plugs no issues for me with hks
