Spark plug Bosch or OEM Honda

I believe BOSCH were the OEM for the spark plugs on these. I went with Copper/Nickel plugs the the originals were Platinum, again I believe, I'm not 100 percent on that. I'm using a shortened maintenance schedule because I use the car for Auto and Rallycross so I'm ok with changing the plugs a bit more often.

I’m working on my 08 GTI FSI and man she loves my paycheck like no tomorrow! But she is the greatest car I’ve ever owned. Congrats you’re going to both hate and love it!!! Check the coil packs! Mine use to misfire all the time. Brought it to three shops before I personally replaced all four and bought nothing but NGK or Bosch plugs.

I use Bosch everytime I can, minus their $90 spark plugs lol

Avoid the NGK’s Bosch or “Volvo” (also Bosch) plugs are way better than the NGK’s.

I had good luck with ngk bp6hs, Bosch w8Bc, champion l87yc and renault oem short thread (yes, really.) plugs. Bosch w8ac used to be good but i had some arrive not working out of the box recently so I'm now avoiding them.

I learned this after installing Bosch plugs in a Honda many moons ago. Japanese cars like Japanese-designed plugs.

Ja tive problema com velas bosch. NGK é melhor.

I tried Bosch plugs on a 1995 NG900. Problem as described. When they state compatible, that might only address mechanical fit. Stick with the original plugs

I personally refuse to put anything Bosch made in my cars. All were genuine Bosch parts from my local parts place that has never done me wrong.

First it was their wipers, paid good money for them, squeeled worse than the worn old ones. Figured it's a fluke.

Then I had a set of spark plugs, they were gapped correctly, but the car ran like absolute garbage and I couldn't figure it out until I put the probably 20 year old Valeos back in and it ran fine again.

Then I had a crankshaft sensor that was bad out of the box, and that was the last straw for me. I don't care if it's coincidence or a bad batch, or if they've improved it since, I'm done with any Bosch parts unless it's NOS from the early 2000s or earlier.

My 2000 with California emissions (regular cat and then two pre-Cats at the exhaust headers) would only run properly with the oem spec NGKs. Threw Bosch in their once and it ran terribly.
