I see. Same with my '00 coils. They went out after a solid 17 years! I think the main reason was that excessive oil basically drowned coil number 3 in particular killing it and causing the rest to follow. Previous macs at Honda did not even notice this when the car went for dealer services and expensive stamps in its book...I promptly cured that by replacing the VC seals with brand new OEM ones then a set of used (but lower mileage - 100k miles) coils from an '01 S2K. Misfire gone as a result though I don't know how much longer they will last.

Good advice Pinky. I've noticed that discoloration as well. I attributed it to oil burning the coil when it seeps passed the plug hole seal (old, hard seals).

A few companies(chasing J's, Circuit hero and Ssworxs) make vented ignition covers for the F20/22 engine made out of titanium, aluminum, stainless steel or steel.

So that is why I see people number the ignition coils on this engine.

Just a heads up boys. One out of 4 Amazon bought Denso "made in Japan" 673 2301 coils burned out on me. I bought an identical replacement and it too burned out on the first pull at only 7k rpm. I'm supercharged.
This makes me so mad that I want to buy the actual, no questions asked genuine AP2/K20 2004-5 coils from Majestic. 30520-RRA-007 $69 each.
Can't be a wiring or any other kind of electrical issue since the car works well and my old OEM coils still run but are dying out at 8k rpm pulls...

NGK Coil U5099 for early AP2 and K20 2004-5. $54.58 on two step performance. For 15 bucks more I'd rather get the OEM ones but still, I like and trust NGK.
Where'd u buy yours?

BTW, anything made in Taiwan is of very good quality, I have found over decades.
