spark plugs

[circmand]

The back plugs are a b&*^% to get to and install Just get a tune up that includes spark plugs it will be better all around

Don't use too much grease, as it can cause misfires...

I used Denso's...

[deermagnet]

It's so easy. I just replaced mine for the third time on Saturday. I use NGK Laser Platinums #PFR5G-11. They come already gapped correctly. $10 each at Advance Auto. The Denso IK16's have an ultra fine 0.4mm electrode that only lasts about 30K miles. The plats will go for 100K, but I change mine at 50K 'cuz it's so cheap 'n easy.

The ones out in the open take about two minutes each to change. The #5 on the pass side takes just a little longer. The #6 is the only tough one, but not too bad. This is how I get at #6. I use 1/2" drive, which is my way. I have the 1/2" plug socket, then a reducer from 1/2" to 3/8", then a 3/8" universal joint, then about a 3" extension. I wrap duct tape around the joints so the whole thing stays together. Ya don't wanna leave anything down there outta sight. That brings it up just above the tube for a 3/8" rachet.

It's really a very easy job.

More than 10 words to explain is not easy.

ehh.. i cant see paying $75 bucks in labor for something i can do myself..

thanks for the tips guys, sounds easy enough, ive got all the tools necessary.. decided to wait on buying the plugs though a retailer at work so i can get em at cost.. i was expecting the plugs to be like 2-3 a piece.. at 7 its worth waiting a day to get em cheaper

I'd post pix of the process but ...

havent done it yet.. ive been trying to find a part number for the bosch platinum +4 plug but nobody seems to have a listing for the VX or trooper? anyone with them remember which number you needed?

etl, just a personal note...

i would never use anything but NGK in my japanese vehicles.

they are designed for japanese vehicles and work the best with japanese vehicles...

tried the bosch platinum 4+ one time in my integra...within a week i went back to the parts store to get NGK's due to the misfiring, lack of power and oil consumption the bosch's had...

I'm not picking or anything, but how does a spark plug cause oil consumption? In my opinion, only two things can cause oil consumption: oil getting past the valves, and oil getting past the rings.
Just wondering. I've been wrong before, once.

If ya do a Google search for Bosch Isuzu it seems like #4417 is the plug, maybe. Some people here have been happy with the 4+ in their VX.

just did 5/6 spark plugs in a touch over 15 minutes.. i was about to tackle the drivers side spark plug closest to the firewall but a big storm moved in real quickly so i packed it in first and just in time.. so ill take care of that one tomorrow..

i ended up going with NGK Platinum plugs thanks to pbkid's advice

[Knigh7s]

I'm running the NGK Platinum plugs myself and also use them in the eclipse. That last one was a pita, but a little patience and you can get it in no prob...

[EDIT]: I just dug out the NGK boxes from the garage, I actually have the NGK Iridium IX, not the Platiums...
