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 went to the dyno today and ended up with some pretty good #'s 321HP 304TQ Car was ran on SPS3 settings boost 9 timing 9 with Sunoco gt100 fuel. Temperature was mid 70's My car: 2003 A4 1.8t quattro ATP/Revo GTRS ATP Manifold Ecode Front Mount Intercooler Ecode Test Pipe Neuspeed Xtreme Turbo intake pipe Neuspeed Exhaust Stock airbox with K&N panel filter stock N75 valve working And NGK BKR7E plugs South Bend OFE SS clutch I could have done better if I had the right plugs (Bosch 3 electrode) and a manual boost controller but im pretty happy overall. Also the car was pulling 0 correction factors all the way through the rpm range so Lemmiwinks could have helped me with some more timing.
I decided to go with the Denso Iridium Spark Plugs Part # 5304#4 and am VERY happy with them. My car runs better than it ever has. These plugs were a little expensive but still less than what the dealer wanted for OEM plugs. I definitely recommend them!
if you're gonna go iridium get the denso's because they (denso) have a smaller tip on them allowing for a "cleaner spark" and therefore a greater chance for detonation....less missfires as someone else has already said....I've run them both and I'm very pleased with the denso's
When it is warm out the IK24's work awsome. But on cold mornings they suck for the first 3-5 minutes of driving.
I put in a set of BP6ES today, gapped to .022", and had every bit the misfiring problems as before, and probably a bit more severe and more frequent.
Don't use those, they suck. The center electrode is tiny, and fouls easily. I've had problems with them, and so have others. They don't last for ****.
