Spark plug Bosch or Denso
I've been running BOSH+ and it feels great!!
I've used Bosch plugs for many years all types and never ever had one single issue.
I've used nothing but Bosch in my 2L and never ever had any issues.
Anyways, I put in so Bosch Tri-Electrodes and Beru coilpacks. Once I got the APR ECU back the car fired right up. I drove it for a good hour and no misfires!!!
In my B3 Vr6, about 3yrs ago, I swapout the NgKs to Bosch Fusion 4-prones and my mileage went from 17 or so to 32mpgs. My car responded better and better mileage.
ive put new denso oem spark plugs and im waiting on my coil packs to come in from ecs tuning and i hope that will fix my problem
I've been using Bosch FR8LDC in my car for years with good results.
Changed spark plugs, wires, cap/rotor with Bosch bits (w7dtc not those crappy +4s)
After too many bad experiences/unhappy motors I wouldn't put bosch plugs in a lawn mower.
I bought some of those and didn't think much of them tbh. My engine prefers NGKs for some reason. Feels smoother and more eager to rev. I noticed with the F5DPORs a 'welded on' tip which looked a bit weak
