Spark plug Bosch or OEM Honda

The Bosch side fires are an AAN plug that has a removable top. I will probably use those, they worked great with my B5 S4.

I've been using bosch FD5POR aka rs2 plugs. I'm quite pleased with them.

Bosch F5DP0R on a T3/T4 50 trim at 25psi daily. Love it.

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.

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

First step, get those Bosch Platinums to a trash can where they belong. Even when I was in Bosch Fuel Injection Training School back in the early 90's, the Bosch Instructors were telling us not to put them in anything unless we wanted to start chasing driveability issues.

I'm a technition with many years under my belt.... and had numerouse out of the box brand new BOSH plugs that upon installing them were dead, not just one but two in the same set, i would then take em out, check gap, and spark test the plug wires and coil, swop them to a diff cylender and bam.. still crap, im not trying to knock them and im not and NGP rep, im speaking from experience

iv had mor problems with a brand new bosh plug then any other plug.. even cheap knock off checker brands...
