    Product Description

    Replace your VQ37's tired ignition coils with a set of 6 new Z1 High-Energy Ignition Coils!

    Z1 ignition coils are direct fit replacements of OE coils that produce more spark energy under all operating conditions. 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.

    • Improved Combustion
    • High-Energy Output
    • Discreet Black Color
    • Increased Reliability
    • Improved Response
    • Up to 19% higher spark energy!
    • Replaces OE 22448-EY00A

    Don't forget the spark plugs! 

    1. Genuine OEM VQ37 Spark Plugs - The plug of choice for stock or bolt-on naturally-aspirated engines.
    2. 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.
    3. HKS Super Fire Racing Spark Plugs - An excellent option for highly modified engines. These plugs are available in three different heat ranges:
      1. Heat Range 8 (Stock) - This spark plug is comparable to the OEM R35 Spark Plugs and is great for highly modified VHR engines.
      2. Heat Range 9 (1-Step Colder) - We like this spark plug for forced induction applications producing 550+ whp, or for use with E85. 
      3. 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.

    Fits:

    • 2009+ Nissan 370Z
    • 2008-2013 Infiniti G37
    • 2013-2015 Infiniti Q60 Coupe

    As I expected, Z1 Motorsports’ ignition coils were perfect fit to my 2011 G37. With new Denso spark plugs, G37 engine gives me very steady idling. Very satisfied.

    March 30, 2025
    My G37 was having a misfire and I tried replacing most fuel system components. The coil packs from Z1 eliminated the issue. The process of purchasing items on their website is a breeze. Also, I’m enjoying the aeromotive fuel pump they offer. Thank you Z1 for what you do and for your many years of service.

    Just had this Z1 VQ37VHR High Energy Ignition Coil pack set installed, has OEM fitment and thus far has performed wonderfully. I haven't honestly noticed any increase in throttle response or spark energy, but if all the the other Z1 upgrades I have already installed are any indication, this coil pack set will continue to perform reliably for quite some time to come!

    Great product, so the Z I purchased had a lot of miles and was looking into getting some issues sorted out, this was on my wishlist and purchased it and swapped them out with these and the car responds way better, all I can say it’s more responsive than having really old coils. Really happy with the purchase.

    I have a 2008 G37S coupe with around 170k miles and I cannot believe how much these coil packs have restored power to my car. It’s way more responsive and just much more strong throughout the entire rev range. I highly recommend these.

    starstarstarstarstar
    October 20, 2023
    Haven't had a chance to put them on but heard good things. They have nice weight to them and the quality seems top notch. Also they each came in the own individual box so i know they made the trip ok
    starstarstarstarstar
    September 27, 2023
    Direct replacement fit. Recommend new spark plugs when installing so that you only have to remove your throttle bodies once (VQ37VHR).

    September 23, 2023
    I didn't need to buy the Z1 high-energy ignition coils, but after reading so many positive reviews, I decided to buy a set of 6 and replace the originals (OEM) with the Z1, and....Whaaauuu... you can immediately notice the difference. My 370z has now much better response and acceleration. The Z1 high-energy ignition coils not only work much better than I expected, they also have a stunning finish. I recommend everyone who has a Z car to buy this product because without a doubt they will love it.

    Honestly I only bought these cause one of my coils went bad and this set of 6 was half the price of 6 OEM ones, but they’ve been working phenomenally and I definitely recommend buying them if you need to replace coils
    starstarstarstarstar
    July 13, 2023
    The quality is A+++ and install was as easy as can be. The car feels a bit more responsive and on WOT the car never skips a beat. I’m beyond happy with the product and it definitely makes all the difference is looks & performance.

    installation was simple enough and good replacement for factory coil packs. Got a check engine light and got the 302 code i think it was, for a bad coil pack. I removed the throttle bodies and some lines to the intake manifold to clear a path the ignition coils.

    March 22, 2022
    I haven't noticed a big difference in performance since my setup is NA, but a big detail I noticed was in the rigidity of the boot and quality of its seal with the valve cover and ceramic insulator of the plug. I've been running original coils for about 190k, and both the original boots/generic $7 boot/spring/fuse kits from retail auto part stores have a lot more bend to them. I have experienced loss-of-spark missfires in the past from boots that are wobbly and/or are in bad condition. These being more affordable than OEM is a plus.

    Purchase was well worth it. I’ve owned Okada plasma coils and I definitely regret buying them. The coils not only didn’t last a year but also had a horrible customer service experience. I was denied of my 1 year warranty. Don’t buy Okada coils! Z1 coils have the same performance as the plasma coils from Okada. You can feel the difference coming from OEM.

    My 370Z has 117,000 miles Changed my plugs at 60,000 But keep my OE Coils At 110,000 started to see RPM gauge stumble at cold starts and my exhaust had a different tone to it At 115,000 the car started to feel strange at coming to stops Finally changed my old worn out coil packs to the Z1 packs at 117,000 and what a difference my car is back to sounding and driving as it was when I got it new Never knew how worn out coil packs can get and how much power loss I was experiencing but these coil packs did not disappoint After the initial start up and test drive my car feels like a new ride once again LOVING THE DRIVE ONCE AGAIN !!!

    Bought a 370z with 75k miles on it and figured I'd change out all the parts that could have something go wrong in the near future. The spark plugs were super clean coming out so it gave me a good feeling nothing was wrong with OEM Coils or the spark plugs that were in the car. But once these went in felt the instant gains. almost done switching all my bolt on's that i'm wanting then off to the Dyno!

    Bought this as my last resort…. I had a weak idle car would stutter at stops. My car was running rich and was very hesitant. The thing that did not helped me was that there was no service engine light so I couldn’t read any codes. I had already changed spark plugs and fuel pump before getting this . After installing this my car woke up once again !! I love It got my car back
