The car started to misfire at boost so I swapped plugs to NGK PFR6H-10 and everything is good now.
Don't use Bosch sparksticks.
I use iridium’s NGK haven’t had any issues.
Just replaced my previously purchased NGK Iridium from Rockauto.com After 100k miles the looked like I put them in yesterday.
NGK Laser Iridium is the Honda spec and what I buy and have had no issues for 5x 105k intervals.
I read that NGK plugs already have a coating on them, so I didn't apply any when I fitted new NGK BKR6EQUP plugs. Torqued them to 25Nm.
The old ones (also NGK) came out easily and I used a bit of tubing to hold the plug as I installed it into the thread, making sure it was threaded on straight before switching to a ratchet and torque wrench to screw down and tighten.
Every one of my internal combustion engines (3 cars, 2 motorcycles, zero turn mower, has NGK plugs.
It's hard to go wrong with NGK spark plugs on Japanese vehicles. That's what I've always done with great luck.
I have a had a couple of NGK spark plugs with very fragile ceramic insulators over the last few years. I suspect like everybody else they are cutting on QC due to that inflation that officially doesn't exist, especially for made in Japan products.
That gap is INSANE, or at least appears to be.
In case you were wondering why those plugs look different, that plug on the left you’ve chosen (BKR5EIX11) is a plug that doesn’t match the longevity characteristics that Nissan originally set. The electrode basically isn’t designed to last as long.
only buy ngk rest is shit
