NGK IZFR6K 11 Laser Iridium Spark Review

Fits perfectly the only small detail was a gap of about 55 but it didn't make much of a difference I just adjusted it from about 42 to 44 for my witch Honda Accord 05 v6 should be between 39 and 44

Recommended by Honda in the manual for my 2003 Accord v6. And since I switched all coils to NGK, I figured they would vape well. But surprisingly, they noticeably increased the engine's vibration at idle, so I went back to OEM Denso spark plugs.

Got these for my Honda and they fit perfectly. The old plugs weren't badly stamped (but they were of a different condition and brand, which I didn't like) so I didn't see any noticeable increase in performance, but they're definitely smooth. As always, NGK can do no wrong.

Worth the price. The Honda dealer asked $350 to replace 6 spark plugs. They cost less than $50 and got the job done in under 45 minutes with no rush. A car with 107,000 miles is now more powerful and runs great. I'm sure MPG will be improved too.

I was repairing the car and one of them broke in the engine head. Strange because the housing was stuck, the spark plug came right out with the magnetic socket I used. I'm about to wait for tools to remove it. So frustrating because they had great reviews and left me without an ATM. Hopefully I'll be fit again by Wednesday.

Arrived quickly, in excellent condition. However, it is important to check the gap on the connectors prior to installation as I had to adjust 3 of the 6 connectors to get the spacing to my machine specs. It's easy to do and I've always done it with every spark plug I've bought over the past 45 years. I still give them 5 stars as the machine has been running great since I installed it a few weeks ago and I've saved a ton of money by doing the work myself. By doing the work myself, I am confident
