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'd recommend getting either spark plug yourself at a parts store, they last much longer than platinum spark plugs and offer more performance. plus the rutheniums, if available for your model year, offer slightly better fuel economy as well. if you want the ones with the longest longevity and best performance I'd get iridium high ignitability, but those can be costly. definitely go with NGK. bosch are also decent and denso are usually oem but I personally prefer ngk.
I put NGK B5HS plugs in mine, no complaints so far.
Torch F7tc took 3-5 attempts to crank. This NGK paired w my Wgen11500 cranks first try every time. Very pleased.
I used NGK laser iridium to replace my probably original 256k mile acdelco plugs. Noticed exactly no difference in performance.
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.
Champion spark plugs are rubbish, not sure why they’re even sold.
