What do you guys suggest for tune up parts (spark plugs, wires, cap, rotor.) One of my managers said that he felt a difference when he put in the bosh +4's. what do you guys think?

 

I think those Bosch 4+ plugs are crap. I've never been convinced that they provide better spark for anything. And if your at high altitude, don't go platinum, they burn out pretty quick.

And besides, if they really were that good, you'd have heard more about the HP gains or increased fuel economy....

 

i got the Champion Truck plug seriers..cool looking black precelon/gold plated ones.. decent price and last a while, and easy to clean and regap for use again,,every oil change i take the plugs out and check them, regap and wire wheel them to clean... this time (in about 400 miles) im gonna get new ones with new wires and gonna clock the plugs so they face the exhuast valve...

 

If you're just replacing stock parts (i.e. not upgrading entire ignition system), make sure you get brass in your cap and rotor. It is a better electrical conductor, and improves spark delivery. For plugs, I run Autolite 3923's.

 

Just so you know, the good cap and rotor set from NAPA has brass contacts. Around $10 for both cap & rotor. I tried Bosch platinum plugs and actually lost gas mileage.... I use the Champion Truck Plugs also, and have them "indexed". I put in MSD 8.5mm wires, $90. You don't have to use these, but Steve00ram360 likes them and that was good enough reason for me to try them....

 

ok, looks like everyone has there own opinion.

 

Bosch Platinum plugs are junk...doesn't seem to matter what vehicle you drive. Be it Ram, Intrepid, Grand Prix, or Bonneville (I own one or more of all of those), they just don't seem to fire well or last even half as long as they're supposed to [:'(]

Champion truck plugs are what I'd recommend. Those and the 8.5mm MSD wires.

 

ok, I know that on my old 2.3 turbo the electrode on the bosh platinums flaked off due to the boost. I ran autolite copper plugs in it.

 

unless you are upgrading everything, i would go OEM, usually the best bet, not that expensive and that's what's supposed to be in there.

 

I also have a question same as they guy above i have a 2000 dodge neon wut tuneup would be the best? Spark plugs, oil? I have 80000 miles on it!
