Plugs

How easy or difficult is to replace the spark plugs. How to do it. What are the best ones. I will apreciate your help, thanks

Pretty easy on my 2001. Depends on your car really. What year?

The originals tend to be rusted in place so they are a pain to get out. But after that, replacing plugs is easy.

I use Bosch Platinum 2's.

The mine one is 99.

I am not sure about your car, but some general tips.
-Make sure the plugs are gapped properly.
-Be very careful not to cross-thread the new plugs. It is very easy to do and getting them out later will be a real pain.
-make sure you get a good "click" when snaping the new wires on.

Otherwise, it is usually easy (unless the intake system is in the way).

Good luck.

Yours will be easy then. Just be careful on the rear plugs as nice sharp, rusted metal parts tend to be very close to them (ask viper04af about that).

Removal of the plugs is easy. Just do one at a time. Remember they come off in counterclock and go on clockwise. They only need to be hand tight (enough so that they won't back out of the sockets). Start with the number 1 plug - the first driverside plug. It's easy to see and easy to remove. This is a good time to replace your wires too. I have 8.5mm accels on my car. Don't forget to re-use the heat shielding from your original wires too.

You are going to need a spark plug socket and a small extension to get to the plugs though since you have to reach between the manifold tubes. If the car is still a little warm (but touchable without being burned), it will help the plugs come out a little easier.

as far as plugs go, i wouldn't run bosch +2's.. i have tried them on two seperate occasions and seemed to lose power with them. i took them out and only 25% or so actually ever fired to both electrodes. I feel they are a waste, but thats just my opinion. I run a standard autolite plug and change them regularly and see good results.

When I moved to the bosch platinum +2s, I noticed a significant increase in my acceleration over standard single tipped plugs. Our different results could also be due to differing years in the cars and their ignition systems differences.

true.. the differant engines do have to be taken into account. fromwhat i've seen, the 3.8's seem to fire better than the 3.4's... but it still doesnt erase the fact that most of the +2's ive used were not gapped correctly from factory, thus causing them to only fire to one electrode, not two. but hey, if you are having luck with them go for it.
