Can anyone give me a recommendation on replacement spark plugs for my 99R? Not looking for any snake-oil plugs, just OEM or comparable..

Thanks!
George

 

OEM Champions listed in the owner's manual.

 

some prefer NGK over the OEM champion

 

I've run NGKs in other vehicles with good success. I may look into it.

 

Resurrecting an old thread here: Does anyone have specific plug recommendations on these? How picky are the engines? Its hard to find the NGK plug specfied in the manual....

 

You can't find NGK or Bosch Platinum 4's on line?

 

Go with the OE plugs. You will be much happier. They aren't cheap, $15.15 each. But, they will make the car run properly.

 

Agreed, I got 8x Iridiums for mine from my local main agent, car ran better. He knocked 25% off for being a JEC member, nice touch....

Amazon.com has the NGK Iridiums under $8.00 Thats where I got mine, and they work great.

 

Do you have a part number on the Iridiums? The Platinum plugs I have been looking at PFR5G-13E Amazon has but will only sell you three for some insane reason. They are limiting the quantity available "so everyone has an opportunity" they said.
