Spark plug Bosch or Autolite

Replace the spark plug with a Bosch. See if it will start and run.

I have a shelf of new parts for a bunch of my VW’s. All the cap and rotor parts I can find are the same for either car. They’re brand new. The plugs are brand new as well. Gapped by the Bentley. The plugs were “black” from trying to fire but not.

I purchased from a local auto parts store for my 07 E550 and SO's 05 E55 - stealership quoted around $1k, parts for each with Bosch Iridium plugs was about $125. Installed new plugs at around 70k for the E550 and OE plugs (also Bosch) looked clean and the gaps were spot-on

I had those on my 2017 civic 1.5t sedan that I had some performance mods done to and they worked great

They're both fine brands, I doubt you'll notice a difference. NGK is most likely OEM for your Civic, but it's not like Bosch is bad, they're OEM in my BMW.

These are Autolite plugs, not Motorcraft. Which means the plugs in this vehicle have been changed before, that probably has a little to do with why it was easier than usual to get these out. By the looks of the plugs and the lack of carbon buildup and corrosion (the two factors that cause these plugs to size the most) I'd say they weren't in there for a very long time either. Going by my experience with Autolite plugs in Fords (very little experience as I work on Euros mostly) if they don't start misfiring right away it's usually within a couple of months.

it was the Autolite spark plugs. Had car towed to my mechanic. They replaced with spec NGK and the car is running fine.

I bought Autolite spark plugs but after researching I should of bought NGK. Right after replacing them when I accelerate my car jerks or misfires when driving. When at an idle I felt my car jerking.

Neither, I’ve seen Bosch plugs fall apart and I wouldn’t trust autolite on my lawnmower.

Installed new Bosch Plugs (WR7DC+), Bosch Distributor Cap, and Rotor. Now the car seems to be having a weird idle sitting as stop lights, and the engine almost shut off while I was backing into the garage. Also she seems like its having a harder time sterting up as well.
