Spark plug Bosch or OEM Honda

Yeah can go wrong with acdelco. I run Bosch in my 93 4.3

I've run Bosch iridium's in all my vehicles (boosted and daily). No gapping needed.

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.

Bosch should be the safest choice for German cars, but avoid their gimmicky "Plus 4" plugs that have 4 ground electrodes, unless that's what the car came with from the factory.

Bosch provides OE for VW spark plugs. Plug your vehicle into autozone and just buy the bosch ones. They come pregapped.

But otherwise, Bosch FLR8LDCU+.

In my experience, Bosch spark plugs are always terrible; fouling out within a month, that kind of thing...

Worst case of electrode wear I've seen was on a set of Bosch 3-electrode plugs in a VR6. Plugs were so far gone, that five of six had triangular shaped center electrodes. Really thought I was gonna gall the head threads they'd been in so long.

I found Bosch platinum plugs misfired intermittently on GM v8s with the optispark distributor despite being identical to the Delcos.
