Reviews of Bosch spark plug

I'm using the OEM Bosch spark plug. I gapped mine to 0.024" as per Bentley and the car seems to run fine.

Recently replaced original spark plug wire set w/new Bosch; wire set, distributor cap, rotor, O2 sensor and Platinum spark plugs

I think that the recommended plug (and original equipment) is probably a Bosch Silver plug, and that is what I would probably stick to if I were you.

the car seems to run really good at the .028 with the bosch plugs

Bosch FR8DC+ perform well and you won't have to worry about seized plugs. You might have to change them sooner.

I've been researching spark plugs and i believe the oem's in Phaeton are Platinum. I am certainly going to verify that and will change mine to Iridium's. For the purpose of better power, performance, and fuel mileage.

I found a set that didnt get sent with my car for some reason when i sold it they are worth the money my idle smoothed out with the bosh compared to the autolite 63's

When it was time for my 80K service I used Bosch FR7HPP222 plugs gapped at .040. The current owner is now at 110K and the car is running great.

For the cars that call for the silvers as the OE plugs, there is no better choice [than the silvers].

about ten years ago, when my Beetle was my DD, I used nothing but Bosch Super (the cheap copper ones) and never had an issue.
