Spark Plugs
Anyone try NGK Part # 4696 (Laser Irdrium IFR5D10) Spark Plug? or NGK (Laser Platium PFR5G-11)? My car reached 70k miles and have problem starting the car sometimes. I think to replace spark plugs can solve the problem..
Any Opinion?
Thanks
Changed mine out at 60,000. The original platinun Beru's are good plugs but the NGK's require less energy to spark and last as long or longer, though I wouldn't go over 30,000 miles on any plug.

I use a 17mm wrench, place behind the boot and push on the other end against the engine block. Use a 15mm wrench end to push the boots back on when the plugs arein, push until you hear a "click".
Do not pull on the plug wires.
Remove the bolt holding the coils and the wire going into the coils before removing the plugs.
LABLE WHICH PLUG WIRE GOES TO THE FRONT PLUG AND WHICH TO THE REAR PLUG FOR EACH COIL REMOVED. Easy enough.
I spent a total of 75$ and about 1 hour on the job for a 320, 12 plugs.
You have to remove the MAS on the passenger side, easy enough.
Good luck.

I got my NGK's over the net at Clubplug http://www.clubplug.net/retail_iridium_ngk.html for 6.50 a piece no tax.
PepBoys also has them for about the same price and you don't have to wait 2 weeks for shipping.
The procedure to replace isn't to bad I thought.

I need to order some. I heard clubplug is a good place...but haven't really checked.
Beside, where you get that couple bucks good deal? I think everyone will like to know?
bad sparkplugs would make your car misfire. it's always good to change the sparkplugs, also consider changing your wires while you are at it.
