Also, make sure you get them started back in correctly and dont over tighten them. When i did mine i tightened up real slow after reading on here about people stripping plug holes out. OR!! plugs blowing out later after a plug swap.

Im pretty sure i put autolite double platinum in (thats all they had) and it seems to like them. Im going to try a diffrerent plug next time to see if i feel a change. Just go slow and take your time and you will be finished going oh! that wasnt too bad

The above pics show the fuel rail off, but I guess I will try it without taking them off tomorrow. While I am in there, will upgrading the cop's make a difference?

mikevm with your mods you are not going to notice a difference in any spark plug.

power (whatever the rest of your sn is) changing the spark plugs is not a difficult task, but after reading this post (and i mean no offense) you might want someone that has a little background to help you out....pretty hard to mess up, but still good to have someone there that knows how to do it.

lol good catch...didnt even see that the fuel rail was off. it is not neccessary to take fuel rail off...but if you want to take it off, its really easy...pull fuel pump fuse crank car over a couple times then take the two bolts that hold it down.

aftermarket cop's are garbage, your better off with the oem ones.

I know i wont notice a gain per say, but ive read alot of different users results from different plugs. So im thinking maybe there is one what will run better than the autolite DP.

well does your car start, idle, run...no miss fires, hesitation, pre detonation (backfire) etc...if it runs good, your plugs are fine. Most of the time plugs are just a personal brand preference. Some swear by ngk others say autolite is fine. Once you get some bigger mods done to the car, then worry about plugs.

Sounds good saving money. One more question before I am square, stock temp or cooler plugs? Hope that wasn't covered already cuz I didn't go back over the thread.

are you running boost or aftermarket cams? then yes colder
basic bolt ons? stock temp

Just figured i'd throw this in here about the COPs

Back in the day of the distributor world, it was highly recommended to get bigger plug wires, and a better distributor...which is still recommended on that setup. The voltage fed to the plugs was generated by the distributor then sent off (distributed) to the plugs...there is loss (resistance) between the distributor and the plug...that is why the bigger plug wires were a big help, they lowered the amount of loss.

On our cars we run a COP setup...the distributor is replaced by sensors feeding the PCM telling the individual COPs to fire at a certain time. Between the pcm and the COP is just two 18 gauge wires....everything is amped up at the COP (cop is basically a transformer) and then fed directly to the plug. This setup causes very little loss, and no need for an aftermarket setup.

Yeah, appreciate it.Jjust remembered seeing some tests Granatelli (sp?) did with some cop's on a GT, and it gave it some more power. I just asked because I know manufacturers will tell you anything to sell their products. Stock cop's and stock temp plugs it is. Thanks for the info, gonna git her fixed up tomorrow.
