Spark

Copper plugs are the best we have found for turbo application, self-cleaning and develop a nice hot spark. We have 6es for those under 15psi of boost Don't be fooled by those expensive platinum plugs that will foul out by the second stop light, these will keep you running strong and won't hurt the wallet either.-Order 4 to make a set

Copper plugs are the best we have found for turbo application, self-cleaning and develop a nice hot spark. 7 es for those running higher then 15psi of boost. Don't be fooled by those expensive platinum plugs that will foul out by the second stop light, these will keep you running strong and won't hurt the wallet either. Order 4 to make a set

8ES are preferred by some who are running extremely high boost or perhaps a lil nitrous. They are 2 Ranges cooler then stock. Order 4 to make a Set.

For years Iridium plugs have brought long life and clean spark to naturally aspirated engines, but unfortunately turbo charged engines have had very little success. NGK has changed the game with there Iridium Plugs specially developed for turbo charged engines. The Iridium tip delivers more spark energy with less power, and last 5 times longer. These are great plugs for moderately tuned cars-under 400HP, they will give you long life with a lot less chance of fouling. If your car lives at the drag strip we still suggest the BPR7ES

If you ever popped the hood of any DSM thats fast you have seen these wires, anything else is a waste of time and money. 8.5mm to deliver excellent spark, and shielded with nice silicon boots to keep from becoming brittle and breaking.

Sometimes OEM equipment can be some of the best designed hardware. And NGK Spark plug wires are just that, thick at 7mm, deliver high energy spark, and have silicon jackets to ensure years of trouble free use.
