I'v got 130,000 kms on my 04 max now and I'm wanting to change the plugs just as a preventative maintenance thing, but don't know the procedure for changing the back 3. anyone have a link to a guide with pictures on how to do the back 3 plugs?

P.S. i did the search function and found nothing.

thanks man, that was about the most accurate response as i could ask for.

 

Let us know how it goes, i need to do mine but i think you need to take off manifold

 

what plugs are you putting in? I just bought the DENSO IRIDIUM Performance plugs. They only last 60k miles but are the best on the market and cost a few dollars less than the OE Iridiums which last 200k miles.

 

Are the DENSO Iridium Performace plugs that much better if they last 140K less than the OE Iridiums?

 

Depends what your goal with the plugs are. If you want them to just do their job and last a long time go with the OE plugs. If you want performance and probably better gas mileage, but only 60k miles out of them, go with the Performance series plugs. This article is what made me choose the performance ones. http://www.automedia.com/Iridium_Spa...ht20010101ds/1

 

Gotcha

 

i was trying to go on to the link but it wouldnt let me....am i missing something???

 

NGK all day everyday guys , dont buy into too much of that hoopla they sell you.

We got cars down here running 8s , cars making 1000whp on a 2jz , and everyone is using good old NGK.

All that bosch , denso , HKS plugs is just pure advertisment for money.

I bet that's exactly what everyone was saying when NGK came out with their first Iridium spark plug. NGK makes more than just the OE Iridium spark plugs as well http://www.ngk.com/results_app.asp?AAIA=1431981 . The Double Platinum is their performance plug not their iridium. If you notice even NGK makes the claim that a smaller tip uses less energy to produce the spark needed. http://www.ngk.com/more_info.asp?AAIA=1431981&pid=15891

 

http://www.automedia.com/ click on the link and in the search type "Iridium spark plugs" should take you to the results. click the first link which should be something like Iridium vs Platinum. Hope that helps.

 

Has anyone used pulse plugs before? if so, notice any increase in gas mileage? power? www.pulstar.com

 

It's not that hard, replace the PCV valve too which is near the firewall. I did this last fall at 100k. Used NGK OEM plugs and saw a big difference.

 

the link to the "how to" page does not exist anymore. any other pages showing how to change the back 3 plugs?

 

Here is what I used, it's for the 5th Gen but it's basically the same.

And that's even on an 02. But is still valid. ^^
