We've put together a Mopar tune up package for our customers. This package will come with Mopar OEM spark plug wires, Mopar coil pack, and NGK spark plugs. This is a perfect package for those who do not want colored wires and want to keep everything Mopar OEM.

Not sure on which spark plugs to go with? Below we provide more information to help make your decision easier.

• Stock heat range (LZTR5AIX-13)- Stock heat range is for cars that are BONE stock with no increase in boost.
• 1 Step Colder (LZTR6AIX-13)- Colder range, is for 90% of SRT-4 drivers out there, who have increased the boost with a good number of bolt on mods.
• 2 Steps Colder (LZTR7AIX-13)- For big turbo, big turbo engines only, in the 450+hp range.

Recommended spark plug gap for the Neon SRT-4:

• Stock Turbo, OEM Boost Level: 0.038"-0.040"
• Stock Turbo, Modified & Higher Boost Levels: 0.032" - 0.036"
• Big Turbo: 0.028" - 0.032"

The higher the boost, the smaller the gap you should be using!
