Currently Running Bosch - Fusions - for Spark those seem to have Smoothed the Motor - 1 step Cooler .
The plug they sent me (Bosch #4417 FGR7DQP Platinum +4) runs absolutely fine on my engine, actually it feels better then before, but I just worried if it is indeed not the correct plug, will it do harm to my engine?
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.
Replaced mine at 40,000 with NKG Platnium and it runs better than ever. I wish I had a pic of the ones I removed. They were baddddd.
I've been using bosch FD5POR aka rs2 plugs. I'm quite pleased with them.
I got the plugs in just fine, and since this was the first time they had ever been changed, the originals were still there. Aside from having the Audi/ VW logos printed on the topside of the plugs' insulators, these are regular ol' NGK PZFR5D-11 plugs (stamped on the metal). The new ones I put in were pre-gapped at .040, and the old, worn ones were at .044 for the passenger-side plugs and at .043 for the driver-side plugs. I'm guessing that the elevated distance/numbers reflects natural wear and metal erosion over time.
i just replaced my plugs and wires from ecs not too long ago. right around mid june. i got NGK plugs and wires, plug type was the one u listed there, i have an AVH. the wires i got were numbered wrong just a heads up to anyone that buys them.
I prefer the NGK 8 or 9's, running them at 19 psi gapped at .018.
i changed the original NGK spark plug with new Bosch super 4 spark plugs. a nice improvement but still far from old good performance.
I've found that the NGK plugs that Canadian Tire has sucks....
