NGK V-Power Spark Plugs SET of four, 03-05 Neon SRT-4 / 03-07 PT Cruiser GT

This is a stock heat range plug. If your SRT-4 is modified and has higher boost levels you should look at other plugs that offer a colder heat range.This exclusive 90 degree designed nickel center electrode of the NGK V-Power Spark Plug produces the spark at the electrode's edges. This hot, clean spark makes better contact with the air/fuel mixture resulting in combustion that is more complete & efficient.

Attributes:

• Center Electrode Core Material: Copper Core
• Center Electrode Tip Material: Nickel w/ V-Groove

These are available in stock heat range, if you have higher boost levels or a bigger turbo you should get the Iridium plugs in a colder heat range.

Stock heat range is for cars that are BONE stock with no increase in boost.
1 Step Colder is for 90% of SRT-4 drivers out there, who have increased the boost with a good number of bolt on mods.

Stock Turbo, OEM Boost Level: 0.038"-0.040" Stock Turbo, Modified & Higher Boost Levels: 0.032" - 0.036" The higher the boost, the smaller the gap you should be using!

Note: This listing is for a set of four spark plugs. Quantity of 1 means a set of four plugs.
