I really want to upgrade. I have to get the exhaust done first then I will see about these. I'm trying to follow the big gains like the volant CAI, Banks exhaust, these coils, and hopefully a tune on an old 08 with 210k miles original engine. Currently have the Nismo R tune CAI but want to switch to the Volant after watching the other videos. Stock otherwise.
Excellent breakdown. I’ve been on the fence about getting these but I thing this would be a nice addition to my Xterra when it comes time to change the plugs
We have not performed instrumented testing ourselves but we have numerous reports from clients that they are seeing improvements in fuel economy with coils and also intakes. It's reasonably common feedback for us but we haven't validated it. Biggest impact for sure is driving style so if you're easy on the throttle before and after upgrades we expect it's likely you will see improvements. Exhaust systems that don't loose any torque likely will help as well, any that did loose noticeable amounts on the low end will likely hurt in stop & go scenarios related to MPG.
Spencer, how much of a difference is there between the OEM Denso plugs vs the Value Advantage plugs? Also, how much a difference do the upgraded coils make with a truck @ 50k?
@@z1off-road Would appreciate if you guys could put it to the top of the list. Need to do a 100k mi maint and looking at what difference there is between the 2 plugs.
We can check for you but you may get a quicker answer from the tech team at info@z1offroad.com. We’re working to bring the R50 model support online formally, hopefully it will be added to the model selector soon.
I’m curious about the durability of these. The increased energy and spark duration will generate more heat in the coils and cylinder head. How long can these coils last compared to OEM spec Denso or NGK? Should colder spark plugs be used to offset the increased heat?
