Reason For Removing Them?

 

Fair question...sorry I left out that info. It was not running well. This was not on a stock motor though. He had Pauter rods, larger turbos and was running high boost. He replaced the Iridiums with NGKs recommended by Todd Knighton and the issue was solved.

 

thanks for the info!

 

Thanks for the write up. I'll be doing this soon.

 

I've been told use nothing but the FR6.

 

nice DIY, thanks for sharing - besides the intercooler removal, any other steps omitted for a NA car?

 

+1 i would like to know the same.

 

wow a lot of work to change plugs.

 

Thanks I had my plugs changed before I found this site. I was told it was a 4+ hr book time at a German car mechanic's shop who is a trust worthy guy. He charges $90 and hr and w/ plugs it was about $500.

I guess most anything you do to the engine you have to remove the bumper. Seems like a whole Saturday for some1 who is fairly mechanically inclined and has never done it. In fact I would say if you are not use to working on engines and cars to just take it to a real trust worthy mechanic. I'm looking forward to getting my house remodel finished and then getting back to working on my own cars.

 

Good reference for my upcoming change on Spark plugs change. I love DIY on any of my cars so this should be fun. I'm just afraid of the codes on Porsches since its all new to me.

Can I upgrade to iridium spark plugs since they last longer so i dont have to change every 30k mi on a 996TT?

 

Great job on the write up!! Save a few bucks if one can!!
