Product Description
Replace your VQ35DE'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-AL61C
Fits:
- 2003-2006 Nissan 350Z
- 2003-2007 Infiniti G35 Coupe
- 2003-2006 Infiniti G35 Sedan
- 2003-2008 Infiniti FX35
- 2005-2008 Infiniti M35

Although we made some other changes along with these and it is unclear how old the previous one were, the engine felt more responsive = better than before.

Day n night difference. Have fbo and needed this cherry on top to complement and supply the extra “power” I needed. Had lots of air and this made it finally pop and bang on the down shifts in my experience. Would 10/10 recommend when u have more than a few mods.

Great set of coil pack. I replaced my original coils for the first time because I was experiencing engine misfires and check engine light code P0300. Replacing them with these solved the issue. Another great product from Z1.

Matched these up with a set of one step colder plugs and it livened my car up a bit. Butt dyno approved. A good buy for anybody wanting to do a little upgrade during their tune up

Although I only had a misfire on #6, I opted to change all six coils. My 2003 Z has 83k miles so I figured to be proactive. Cars runs fine after the swap.

Parts delivered in a timely manner, all safely packaged. Replace all six coils, even though only #6 was showing a fault. Since the Z1 units are rated 19% higher output than stock I chose to replace all six. After about 2-1/2 hours they all replaced and the car run.

My stock ones were still good but these are much better when you are building the engine paired with the upgraded spark plugs and possibly new valve covers and gaskets while you’re at it.

These work great, fit great, look great. Seem to help also on the upper RPM on the Rev-Up, smoother quieter, more consistent power. Great product, if you have some miles on your car, which you do, it's a 350z. Buy these and some plugs for maintenance. We went one step colder on the plugs and these, and it was a great maintenance investment.

Ordered, shipped and received, all in quick fashion and great service. The new coil packs were installed easily and power is more linear, as is throttle response at WOT. Replaced the original 2006 coil packs on my G35 with 100K miles. Great upgrade, highly recommend to any G or Z owners.

Yo, these are a must have coil pack for your 350z/G35... Much respect to Z1 R&D dept.....wow my "G" runs, idles and feels linear with all my upgrades and mods. I notice my car doesn't run as rich on the exhaust end either. I do feel a quicker response on the pedal and for the price you can beat the advantage it provides....I promise you won't regret it!!
