370z Z34 Z1 Motorsports High-Energy Ignition Coil Pack - Set of 6

This increase in spark energy is critical for ensuring proper ignition and combustion, particularly while operating an engine at wide open throttle. Greater spark energy is especially important in forced induction applications where high boost pressure can blow out spark, resulting in loss of power and poor running conditions.

From basic bolt-ons to forced induction applications, these coils will help ensure you are getting the most output from your vehicle.

Don't forget the spark plugs!

Genuine OEM VQ37 Spark Plugs - The plug of choice for stock or bolt-on naturally-aspirated engines.
Genuine OEM R35 Spark Plugs - Z1 uses this plug on high compression and forced induction builds because of the proper gap and appropriate heat range. These are an 8 heat range and are pre-gapped at .028" which is perfect for highly modified VHR engines. This is, by far, the most versatile and economical option for full bolt-on and tuned applications.
HKS Super Fire Racing Spark Plugs - An excellent option for highly modified engines. These plugs are available in three different heat ranges:
Heat Range 8 (Stock) - This spark plug is comparable to the OEM R35 Spark Plugs and is great for highly modified VHR engines.
Heat Range 9 (1-Step Colder) - We like this spark plug for forced induction applications producing 550+ whp, or for use with E85.
Heat Range 10 (2-Steps Colder) - This plug is suitable for 10 max boost racing applications on race gas or ethanol blends, or builds with 2 power adders like boost and nitrous.
