Description Technical Specs Extended Information
AUTOLITE 103 NASCAR Developed Colder Spark Plugs Many V6 Supercharged owners are requesting Colder Plugs but they are so hard to find in Australia. We have taken the liberty to order in bulk quantities of the AUTOLITE 103 NASCAR Copper core Spark Plugs from the USA which have been pre-gapped to 1.0mm for best performance. Running a Colder Spark Plug allows for you to run more boost. Going one to two heat ranges colder allows you to go upto 1.5psi MORE BOOST ! This means you have the potential to make more power on the same fuel. These plugs are not available in Australia, they have to be ordered in from the USA. We have taken the hard work out of it for you and made them easily available to purchase from us. These plugs are also Highly Recommended for BIG BOOST applications like the 18-24psi we are now seeing. Notes: These Autolite 103 Spark Plugs are classified as 2 Heat Ranges colder in USA climates
