rmac24vdohc Posted September 17, 2002 Report Share Posted September 17, 2002 Any recommendations on wires and plugs for the 3.4 DOHC? I was planning on going with NGK v-groves and Magnecor 8.5mm wires. Cost is no object so I want to make sure I am putting the best product in. Also thinking of replacing the O2 sensor since I will have the engine rotated. NGK claims to make a good one of those also but they are $50 on carparts. As for the engine, I have noticed the thing is running much better since I started using Mobil 1 full synthetic and K&N oil filter. Of course, thats what I used on my old cutty and I was at 224K and running strong. Still looking for a boot cover for top with no luck from many junkyards all over the country. Oh well.

MaD Posted September 19, 2002 Report Share Posted September 19, 2002 magnecor 8.5's, Delco Rapid-fires, Delco o2 sensor, Mobil 1 full synthetic, and delco filter or better. (Although I think the "other" filters may be too "free-flowing", So, my opinion: stick with delco.) -MaD- Quote Link to comment Share on other sites More sharing options...

GnatGoSplat Posted September 25, 2002 Report Share Posted September 25, 2002 There's really going to be virtually no difference whether you spend a ton of money on fancy plug wires and plugs, or if you stick to the OEM stuff. Delco plug wires last a LONG time. Well over 100k. If you want a long lasting plug, get the Delco Platinums. I pulled a set out of my truck at 106k (original plugs, previous owner told me he never changed them) and they were PERFECT with perfect gaps. I only changed them because I already bought a new set and they supposedly only last 100k and I'd already gone 6 over! Boot covers are still available, but cost $500. OUCH!
