Changing Spark Plugs for 04Forenza

windnad29 · 07-21-2008, 11:56 PM

I have a couple of questions that I know someone can answer. I am a novice when it comes to doing things on my car, but I am learning.

1.) When and how ofter should I change the plugs?
2.) Are they simple to change or a pain in the ass?
3.) What are the best plugs to get when I change them?
4.) I found the distributer cap but the wires run under the top cover. Do I just remove the cover and they are there or since the engine is not sitting like a normal car, are they in a weird ass location?

Thanks for any information is advance. I have learned how to do quite a bit from this site. Any help is greatly appreciated.

I changed my spark plugs at 30k per the manual, they still looked good so they could have stayed longer (I drive mainly freeway).

The OEM plugs are supposed to be the best, we share them with BMW's mainly but they are hard to get. You'll probably have to order them from a local auto parts or get them mail order.

the best kind of spark plug is the iridium type. there are a few companies that sell plugs for the reno/forenza. off the top of my head: ngk, e3 and those new pulstar(i think thats the name)i just read an article where a car got +3 hp from the pulstar plugs. but the general consensus is iridium.

What are the part numbers and how do we get ahold of them. I live in Canada and its extremely hard to find spark plugs out here.

It seems there is a hp gain with the Pulstar plugs:
