To make a long story short, I bought these for my car not long after I had it. I didn't know much at all about cars then and I thought I needed new plug wires so I picked these up. I blew the motor a while back and got a hatch so the car sat for a long time, put a sohc zc vtec in it and boosted it and used those plug wires again and the #1 plug wire has pretty much failed. When under any kind of load, it stops giving spark at all. I through my stock plug wires back on there which have over 80k on them and it's running perfect now. FUCK APC shit. Just for the record, I don't own anything else like that. I got rid of it all a long time ago lol.
