I think you'd be suprised if you used the Iridium Plugs; I was in the same boat as you when the only thing that was available was the 3330r.

I use the 2668 NGK Iridiums in my supra; and they can be bought at any advance auto parts.

 

All you need is a lift and basic tools. If you are standing under the engine, you can reach up and remove all the coils and plugs...it's all right there and easy to do - I've done it without any problems.

 

I knew there was a catch If only I had a lift in my garage. I'll bet the difficulty factor goes way up without bumper removed and no lift. Going to do my plugs in the next couple weeks.

 

The advantage with a lift is you can see everything really well and work easily. I have never tried it without a lift, but I'll bet if you can get the car up on blocks and jack stands to gain some room under there, it's probably not that bad with a good light source. I would try this first before the other route of removing everything.

 

Word of caution for tuned cars: call your tuner. I had a flash in the past that assumed a certain type of plug (bosch fr6), and car did not run all that great when I went with the Densos. I would use the plug that your tuner recommends as compatible with your software.

 

I ran ngk B_EV and BR_EV (heat range in place of underscore) in most every performance vehicle I've had since the early 80s.

When I say that, I just slapped them in without regard to anything other than length and even fudged on heat range by running far too many steps colder and never had an issue with fouling.

If it fit, I put them into anything from a j-ported 1974 13-b rotary to most every crazy boosted car I've owned and they last until I sell the vehicle or build something else for it.

I'm down to my last 20 from the hundreds I got on clearance from electrodyne in 1988 and I'm not even sure they make these amazing plugs anymore.

That said, I'm running copper ngks bpr7es in my current 280zx turbo engine'd infiniti because it's power level is not intense enough for anything more.

 

I don't have a 996tt yet (buy it friday, storing it until April), but what tools are we talking about? I've heard you need a couple of different styles of allen (long/short ball heads and super short allen). I'd hate to get the car up on a lift just to find out that I need to run back out to the store and buy tools... I hate when that happens.

 

I do not recall exactly...there are allen head screws on the coils, then the spark plugs take a spark plug socket. But nothing special, maybe an angle socket drive, I am not sure. I have only done it once and did not pay attention to the tools...

 

my porsche shop charges 4 hours to change them out and they remove bumper and IC
any DIY with pictures???

 

yes someone ought to make a video and sell it!! I'm about to change my plugs and not sure what route to take.

 

John,

can you make a video and I will be the 1st person to purchase it, being I am planning on doing my plugs in a couple of weeks!

I am serious! Lay out the tools that would be needed and go step by step I will be the 1st to call you with my credit card for $40.00!

Thanks

:-) Bobby...I am planning on doing mine again soon. I will try to remember to list all the tools and make notes on the proceedure. I'll post it once I do it.

I do recall that with our SpeedTech exhaust there was plenty of room to do it and it went very quickly and easily for me. I have a feeling with the OEM exhaust, things are probably a lot tighter and harder to access.

 

john when i did mine it was the tightness between the heat shields and the turbos that was a huge obstacle. almost impossible to get my hands in there. honestly removing the bumper cover and i/c gives me a chance to inspect a few things, check boost hoses and the plugs are super easy to get to. i also had 2 stripped allen bolts on 2 coil packs that had to be drilled out. no way that could be done from underneath

 

Please video or take photos step by step.

 

presto changeo.
