Spark plug BERU or OEM Honda

use beru plugs rather than Bosch, a lot of Bosch plugs sold for this application has the wrong heat range which can cause misfires.

Yes, a bad spark plug, incorrect type of spark plug, or a wide spark plug gap can cause a coil to fail. If electrical resistance in the secondary ignition circuit is too high the coil must generate a higher voltage to fire the plug.

I've been using beru rs7 plugs without any issues.

Only issue I’ve had is having 2 spark plugs blow out. The first time required a replacement head and the second was fixed with a helicoil. Most reliable vehicle I have owned.

I have an aero 50. I don’t recall what’s recommended on it, but when I was living in the Pacific Northwest, I found that while using premium, it ran significantly better. Smoother idle, better acceleration.

Yup, these are great. Just be sure you gap them to APR's recommended gap of 0.024" ±0.002" or 0.6mm ±0.05mm. If you want 1 step colder plugs, not needed on your setup, but if you do for the future in Stage 2+. For 10$ more than the OEM NGK you can get the BERU.

I remember the first time I did anything besides oil, it was spark plugs and power steering fluid on my old accord. Starting it up after had me nervous, second guessing everything I did.

I have the beru side firing and they work just fine.

I ran Beru RS7 plus which are one step colder when I tuned stage 1 and they didn't last at all. Might have been under 10,000 miles. Recently went with NGK plus that APR reccomends for stage 2 and so far so good. No misfires since.

I swapped out the oem plugs for Beru rs7 plugs when I went APR stage 2 at ~3k miles. The car ran well. Fast forward to the present with over 18k miles and is20 swap, and I noticed a few stumbles at idle. Nothing major but I figured I'd change them since APR recommends 10-15k mile intervals (visually the Beru plugs looked fine).
