This write-up will help you make your own Audi R8 Coil Pack connectors. This version is very nice and clean. You can also hit up Nathan Davis on Facebook if you would like for him to make you a set.
Important Note: On the VQ35DE (2002-2008), you will need to use NWP Spacers for the Coil Packs to sit properly. The Gen2 VQ35DE (2009+) do not require spacers. You will also need the adapters to plug them in or make your own by splicing directly.

Audi R8 Coil Pack Advantages:
50,000 volts compared to Nissans/Infiniti 30,000 volts.
Some measure it with Kv so Nissans coils put out 21Kv while VW coils put out 30Kv
Quicker Heat dissipation. (Because of its metal body construction it can quickly dissipate heat. Nissan OEM body is made out of rubber that isolates heat instead of disperses it.)
More complete burn of the fuel mixture compared to OEM Nissan which equals to better MPG.
Idle Stability Improved
NO CEL (Check Engine Lights)
BEST PART ABOUT THEM IS THEY ARE CHEAPER $$$ than Nissan OEM yet they are much better.
Looks 10000% Cooler than OEM Coilpacks
Now the coil packs price varies due to different name brands. They range from $132-$216 for a V6 engine. Below is the link of the coil packs below so you can see the prices and brands. Doesn’t matter which brand you use. They all make the same exact power.
After seeing many cars in the Facebook Maxima group, and some in person at shows, influenced me to doing many things I did to my Maxima. I did a little different styling to the things I did whenever I could to make the mods I did a little different than others, like the molding of body parts, and custom paint theme.
The reason I got the car was because I really liked the lines of the car, and the rear with the spoiler when I saw it at the dealer. The OEM wheels style also made me like it. I am even in more love with it now after the things I have changed and added to it. It has a nice sporty/mean clean look to it.
The first things that I did to my maxima is what got me started on it, and just went from there to make it the way I wanted it to look. I had the Stillen Front lip for the Maxima molded to my OEM bumper, to make it seamless, and a clean look as one piece. While that was being done I also had my headlights modified for the first time to add a high beam retrofit, change OEM HID lenses, demon eyes, halos, and paint the inner shrouds silver.
I did the molding of the lip to the bumper because I saw other Maxima’s with the lip screwed into the bumper edge and being held on with 3M tape. You could see gaps, and the screws. It wasn’t as seamless and smooth as I would like, so I decided to look into getting it molded. I found a awesome body shop that could do what I wanted. Precision Collision Center in Rockville, MD. They did it, and made it even better than I expected it to turn out. It turned out so smooth, very clean, and looks sporty, but also like it was made that way from factory. After they did the front lip, I had them mold the rear diffuser into the rear bumper a Month after they did the front lip.
I did my headlights because I liked the halos I saw on others, and I wanted a sporty look to them. I wanted to improve the OEM HID Low beam light output and have a brighter high beam output, so I had the high beam retrofitted to be a HID. I wanted to get rid of the chrome look in them, so I had the inner shroud painted silver.
It went from there with the things I have done. I have done all this in 3 years of ownership. I have changed and added many things since the first mods 3 years ago. I have some things I’d like to still do to it. I really enjoy driving the car and enjoying the things I have added and upgraded to the car.

For all you hardcore Nissan/Infiniti enthusiasts, there is finally an open-source solution that allows you to modify and flash ECUs! With a $10 VAG-KKL cable, you can basically flash your own ECU and tune it your to personal comfortable without breaking your wallet. The average tune costs roughly $600+ these days. Since you’re modifying the ROM yourself, there’s no vendor lock-in and you are free to do what you need and want. Great for those who have knowledge of tuning and want to tune their own vehicles!
Applicable Vehicles:
2000-2001 5thgen Nissan Maxima
2003-2003 5.5gen Nissan Maxima
2004-2008 6thgen Maxima
2009 7thgen Maxima
2002-2004 Nissan Altima
2005-2006 Nissan Altima SE-R
2003 Infiniti G35
And various others……
Links to Tool/Software that you will need (Click links to Download):
You will need to buy an OBD2 KKL VAG-COM 409.1 USB Cable. It costs $10 or less.
It’s all based on the ROM size. If the ROM size is 512K then you should use the 7055_35 kernel. If the ROM size is 1024K then you use the 7058 kernel.

Which ECUs Will This Work On?
Most gasoline Nissan / Infiniti ECUs from ~ 2002 onwards share very similar ECU hardware, based on SuperH microcontrollers manufactured by Renesas (previously Hitachi). This project supports ECUs that use the OBD-II “K line” signal for diagnostics communications.
How Does the Reflash Process Work?
The process is carried out entirely over the OBD-II “K Line” serial communications link through an undocumented set of manufacturer-defined extensions to the standard ISO14230 protocol. Recently, the necessary commands have been reverse-engineered revealing the required steps:
Establish connection to the ECU.
Send the first stage data payload: this is the “kernel”, a simple program that will receive commands and data for the reflash.
Make the ECU run the kernel. From this point on, the kernel runs from RAM and effectively takes control of the whole ECU.
Send the reflash commands and new firmware data to the kernel.
Reset the ECU: the new firmware will now be executed, and the kernel will be completely removed.
Kernel Features
The basic kernel is an implementation of an ISO14230-compliant protocol with extensions. It implements the following requests:
Fast ROM dump (tested up to 5.4 kB/s; typical speed is ~100 B/s without a kernel)
Read ROM/RAM/external EEPROM
Write to RAM
Erase flash ROM block
Write flash ROM block
Requirements
The basic reflashing kernel will support gasoline ECUs with:
SH7055 or SH7058, 0.18um microcontrollers (the most common types)
K line wired to the OBD-II connector pin 7
Unfortunately CAN-only ECUs are not currently supported.
Host computer:
OS: Linux and Windows are known to work; Nisprog is based on freediag source code which is cross-platform and should run on most Linux/UNIX flavors.
Connectivity: a simple USB-OBD adapter is required. These are the “Generic dumb serial adaptors” described in the freediag docs.
OBD2 KKL VAG-COM 409.1 USB Cable
Limitations
There are several important points to be aware of when using Nisprog:
The ECU is a safety-critical system in a car. Reflashing an ECU can void warranties, reduce the vehicle’s reliability, and cause a whole variety of undesirable consequences. Use of this project and any associated tools (freediag, Nisprog, etc) is of course entirely at the user’s risk. Standard disclaimers apply.
Reflashing an ECU may be illegal in some areas. Responsibility in this matter lies again with the user.
Diesel ECUs are not supported, they are entirely different.
Tuning and modifying ROMs are complex skills that can only be acquired through significant investments of time and effort!

So here it is guys! Car is finally tuned on the dyno with no CEL! Car runs amazing so happy with the results. Made 281WHP/262TQ SAE corrected. To many of you guys may seem low but to me it’s great numbers. On the streets it’s totally a different story.
There was a time where 6-speed swaps for the Nissan Maxima were only available for 4thgens, 5thgens and 6thgens. After 2006, Nissan no longer offered manual transmission options. All-new Maxima’s now come with the CVT transmission. While the CVT provides a smoother ride and improved fuel economy, it definitely takes away from the 4DSC experience.
But don’t worry. Those times have certainly and FINALLY changed. The 6-speed swap is now officially available for the 7thgen Nissan Maxima (2009-2015). We consider the 7GM 6-speed the true meaning of a 4DSC. It has a balance of power, luxury and comfort.
These types of projects are the ones that fuel the community into modding their Nissan Maxima’s. The Maxima world was quiet for a few years and thanks to these guys and shops, the Maxima community is back and better than ever! So who will be the next swap? Be sure to keep us posted.
This is only intended for a providing a reference to the list of core parts used in the 7GM 6-Speed swap that was successfully completed by Gerson Flores & Sunday Ortiz. It’s not a how-to or step-by-step process. Please only attempt to do the swap if you are mechanically inclined and understand the Nissan FSM (Factory Service Manuals).
Please note that all of these items were purchased brand with the exception of a few parts (custom & discontinued parts). The total cost for all the parts below adds up to approximately $4,522.00. You may be able to find parts for much less and save money.
Recently, the belt tensioner on my 2009 Nissan Maxima had seized. I was getting a slight noise from the belt and I decided to swap the belt. When trying to swap the belt, I couldn’t really move the pulley to take the belt off. If you have a 2009-2014 Maxima, you need to make sure you get the right one. The first one I ordered was incorrect and use for 2016+ Nissan Maximas. The one you need is 11955-JA10D or 11955-JA10C (same part).
