QX80 + mods

My QX80 as it currently sits with the 22" KMC KM704s w/Goodyear Fortera SL 285/45/22 tires. I also got the chance to DIY the front grill to emulate the midnight black grille option from Infiniti.





With the aFe bolt-on mods (catback, CAI, TBS) already done, sending in my ecu dump to Uprev since the QX80 isn't a core vehicle. Once Uprev patches the ROM, Joe from CajunTuning will dial everything in.

I've also been in touch with Loren from Rotora regarding the Big Brake Kit for the QX80 (8 piston front, 6 piston rear). Although the price was tough to beat when compared to other brands such as Brembo, Wilwood, etc. who only carry a front kit, the Rotora is a complete front & rear kit. I'm hoping for the price to drop just a bit.

Nice!!!!!:)
Thanks.

Just an aesthetic upgrade; LED rear bumper lights. I missed having the OE rear fog lights that were on my Audi and MB. I even installed a set of Morimoto 5Stop LED brake lights on my previous Armada to work just like rear fog lights; those were really bright and wish these on the QX80 were just as bright.

I have them tapped into the OE tow hitch harness to work in unison with the park lights I but plan on wiring them up with a separate switch when I have the time.

Sorry guys, here's the link for these LED lights:
https://www.ebay.com/itm/173226201613?rmvSB=true

Really simple install, as it has (3) input wires: (-) ground, (+) running lights, (+) brake or signal.
I didn't wire it to run like OE tail lights where its dim when on with running lights and brighter when the brake or signal input is triggered. I bypassed the running light input wire and connected the second (+) input to stay brightly lit as pictured.

I didn't want to start another thread but over the weekend, I went ahead and used the CRC GDI intake valve cleaner.
Since the 5.6L V8 in our trucks are GDI (gas direct injection) motors, the backside of the intake valves are no longer sprayed with fuel and the buildup of carbon deposits take place. This is common on all GDI engines, not just Infiniti.

While fuel system cleaners such as LiquiMoly Jectron (my personal favorite), BG 44K, Techron help maintain and clean the fuel system, they no longer have the "cleaning" effect on the valves of a GDI motor.


***Since I have an aFe CAI, I just loosened the hose clamp attaching the CAI tube onto the coupler and slipped the CRC built-in straw to face the throttle body.


Just follow the instructions on the can. You'll need another person to help out so that one can spray into the tb chamber while the other sits inside the truck and keeps the rpms from dropping (1500-2000 rpms).

On my QX80, an increased amount of white smoke/exhaust started blowing out during the first two intervals of spraying but I've read and been told it will vary on how dirty the valves are. By the time the can was about 1/2 done, there was hardly anything else blowing out the exhaust.
I let the truck sit for an hr. as per CRC's instruction and after an hr. passed, it was time to take it out for a good drive.

My initial feedback: I immediately noticed an improvement in throttle response. Even more satisfying when I went WOT merging onto the highway for a "spirited" drive.

I'm definitely adding this DIY procedure to my list. Considering I live in NYC and the majority of my driving involves plenty of stop and go traffic, this will keep the intake valves routinely maintained.

Mod completed! Done, Done, and Done!
Looks nice.

Can you or someone provide more details on how to do this? Or do you have more install pictures to share to make it easier for some of us?

Or can someone do a small writeup with pictures to go along? This is really nice and I am interested in buying a set.

If i can do it, you can do it with ease bro, because its that easy.

The LEDs are specific to LH/RH. That will be obvious when you get them.

There are 3 wires. One ground, one for lower lead output, one for FULL output.

You tap the wires into wherever you want but what primo did (and myself) was to tap into the trailer hitch wires.

You remove the hitch cover finisher. On the plug cover are the pinouts for the hitch wiring.

The way i connected up was using ground and parking light wire on the hitch to the ground and the highest led output wire on the LEDs because i wanted the leds to be , as primo did, as rear fogs, so they are highest output when the park lights are on.

Obviously you can set them up to light up full when you apply the brake , and have them off or even on the lower output when not braking—or anywhere in between.

There’s not really a need for install photos. There’s a screw that screwes the leds into the lower bumper cover.you use those screws for the led lamps when you attach them.

Again, you should have ZERO issues with the install because you are handy on the car, as ive seen in your posts across multiple nissan forums.. :)

do you remeber which particular wire (color of wire) you tapped it into? Did you use the tap a wire? Thanks much.
 
Just bought a used 2016 QX80 last week. But been an Infiniti owner since 2006 first with my G35 and then a 2012 FX35.

Looking forward to installing the Ebay rear bumper LED reflectors next week. I have this set on my FX35 and Morimoto 5stop on my Armada. For all of them I never tapped into any factory lights.

For the Armada I ran a wire from the front to the rear and its connected to a 12v cigarette socket which has a button to turn it off / on.

For the FX35 I ran the wires from the LED reflectors through a gap between the bumper and chassis and into the trunk. There I connected the wires to a 12v cigarette socket plug and its powered by the 12v power outlet in the trunk. This outlet only works when the car is on.

I plan to follow the same setup as the FX35 on my QX80.

For reference: https://www.ebay.com/itm/12V-Male-C...hash=item521de00ec7:m:mSBP6cIgcMTggXXFaAkP2ng

I just saw yesterday (just happened to have the car on and the lights on) that one of them has some leds that are not coming on. I expect this but wanted to see if you experience the same thing primo...
I have the same issue on my Fx35. The passenger side LED reflector has about 12 leds. 2 of them are ON but fallen off the board so they are dangling inside the reflector.

I got rid of those lights awhile back; same problem you experienced. I actually replaced them with an entirely, different set that has been problem free for some time now. I have a short video clip of the rear bumper sequential LEDs but not sure how to post/link the video. They look and function so much better too.

C’mon PRIMO!!! Can’t tease a brotha like that! :) you know I wanna see.

Yeah i guess I expect them to fail but i ordered a new set from a different fleabay vendor when I posted my initial post there a week or so ago and got them a couple days ago. To lazy to wire them up at the moment, but am interested in your setup.

You can post a link on google drive or Dropbox and create a link that people can use to view. And there’s always YouTube!..

@clint,

Welcome sir. Thanks for your post on your experience with these. The leds are not dangling in the housing of the ones I have , just one side has some that are out.

Looking to see what primo has done before I go and install these new ones... :)
