I'll be ordering the NOLOGY plugs, since the best conductor is silver.

 

If the price of these cars goes down much more, those twelve silver electrodes will be worth more than the car.

 

HAA, so true.
I didnt know that about the plugs. i was afraid to mess with them cause the iridium is so thin. But i will pull them out and gap them tomorrow. Thanks

 

There you go...no plug is ever gapped exactly all the time...you should always check this before install...

 

hey how hard is it to do work on the plugs? yall talk about it like it is as easy as adding washer fluid but i have heard its a royal pain in the a$$, and help? thanks! JR

 

plugs aren't hard overall. It;s just the ones in the rear towards the firewall are the hardest to get to.

Wobble sockets and some extensions will be your friend for those.... unless you want to pull out the whole motor

 

I got a set of NGK Iridium plugs (1 step colder) and Magnecor wires from NeedsWings 2 weeks ago for $235 shipped.

My mileage was steadily decreasing and power was noticeably down - put the new plugs and wires and the difference was amazing. MUCH more power and my mileage has immediately gone up over 4 mpg, even with the 'playing around' I've been doing with all that extra get up and go! I didn't see anything wrong with the plugs or wires, but there must have been some problem...

It was not hard at all to change them - took me about 1.5 hours at a leisurely pace. All I needed was a 5/8" deep well socket, 6 in. extension, ratchet, T-30 torx driver, and a .039" spark plug gap wrench (per my n/a manual):

- pull the low-voltage wires from the tops of the coil packs - secured by a wire tie
- there is a vacuum line on the driver's side that needs to be disconnected
- pull the coil packs - you will need a T-30 torx
- disconnect the plug wires from the coil packs - remember the top coil pack wire goes to the front plug
- pull the wires from the plugs - pull straight out, don't twist them. Be careful on the 2 furthest back - they can be knuckle busters...
- blow the dirt/dust out of the plug holes with compressed air
- replace the plugs
- clean the metal on the back of the coil packs and the valve cover where the coil packs meet
- starting from the back, put the wires on the coil packs, then on the plugs, making sure you hear/feel the click to ensure they are completely on
- reinstall the coil packs and low-voltage wires - secure with a wire tie
- reconnect the vacuum line if you disconnected it
- repeat on the other side
- after driving around for a day, check to make sure all the wires are still seated on the plugs and the coil packs

Of the 12 plugs, 5 were gapped incorrectly out of the box, but only by a couple thousandths.

 

Thats an awfully large gap.
I gap everything to .030 but im used to working on boosted motors, lol
