Spark plug Bosch or NGK

OEM plugs are NGK... they are the only ones that actually work. you can use copper over the platinums to save a few $$, but you'll be changing them more often. as for wires, the same, use OEM, I am and I have been running a stg III s/c kit...colder, but still NGKs, and BERU wires.

I run the F6DTCs and have great results with them

I've run NGK BKR7E's, NGK BRK7IX's, Bosch FR7LDC, and Bosch F7LTCR's. Of all of these plugs I noticed the best performance out of the F7LTCR's.

today I installed a NGK BK7RE to my jetta, and it feels great. I like them a lot, considdering I haven't change my stock sparks .

Spark Plugs (NGK) 7 heat range - OEM Honda Timing Belt, water Pump, oil pump, headgasket, and engine gasket set - Fuel filter - Valve Adjustment done by acura cost $175

the BKr7e's NEED to be switched out with every oil change (IMO).. The new plugs feel great and look great on vag logs (less timing pull than seasoned plugs)

I switched to a Bosche plug F7LTCR $4.41 a piece from rockauto.com. They last 4 times longer, and run much better than the BKR7 series.

Bosch FR8DS plugs are stock aba (2.0L 8v) plusgs and are awesome.

I have ran BKR8EIX and i noticed no diff switching to bkr7e.

i've got some bosch silvers...and this happened after about 12k miles and currently (3k miles) later i'm getting similar symptoms as before.
