I just installed these aluminum valve covers on my 5thgen Maxima. AND YES, THEY ARE ALUMINUM! The brand is MITZONE. They are well-made and come with gaskets. I have no leaks or problems so far. They are also very sturdy/solid vs. the crap plastic stuff. Highly recommend.

These brackets will guarantee the proper fitment of Akebono calipers on your Maxima or Altima. Say goodbye to pad overhang and knocking off wheel weights when running your 18s!
The kits will be made out of 6061 high-strength aluminum. I am currently in talks with the machinist to see if I can do a separate run of steel brackets though. I was quoted $45 USD more (subject to change).
The aluminum kits will cost $225 plus shipping and PayPal fees. ($50.00 Deposit Required)
Important Note: These brackets for only for the front calipers. The rear Akebono calipers are plug-n-play but only for the 04+ Maximas/ 05+ SE-R Altimas.
Improvements (Over Previous Brackets):
Mounting holes to the knuckles have been shifted to the correct spots to fix the pad overhang problem.
A notch has been made to clear the curvature of the caliper as it was not allowing it to seat on the bracket properly.
The caliper mounting holes were oversized. This is also corrected.

This build was completed by Stephane Asselin back in 2008. Yeap, over 10 years ago. It was the very first Supercharged VQ35DE Nissan Altima in the world originating from Québec, Canada. It also has a 5-Speed Manual to 6-Speed HSLD Manual transmission from a 2004 Nissan Maxima. Everything was done by Stephane himself except the custom alternator pulley which he had made by a local shop. On the 1/4 track, the car ran 12.614 @ 110.730 MPH on 5.5-6 PSI of Boost.
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!

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.
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
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.
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.

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!
UPDATE from Robert Mandru: Have both the 300zx and 350z bracket adapters. They will NOT clear with Evo X 2 piece rotors, maybe just 1 piece. Even with one piece it still wouldn’t clear the inside, rotor too large with the 350z/G35 adapter. The EVO X top hats are too big and will not allow the calipers to bolt up. Probably could do it with the 300zx adapter without modding the caliper but for god sake, you have smaller bolts that are supporting all the strain coming from holding the caliper in place during braking conditions. Not worth it.
In simple terms….. do not bother with the eBay 300zx Caliper Adapters
If you are reading this article, you are very likely trying to resolve P0420/P0430 without having to spend a lot of money on the issue. Most of the time, the codes are due to a bad clogged catalytic converter or bad O2 sensors. Before replacing the O2 sensor, be sure to do the spacer fix modification first because O2 sensors are not cheap.
There aren’t usually any drivability issues associated with these codes. For most people, the first sign that anything is wrong at all is the check engine light. Below are the typical check engine lights you would normally get:
P0420 NISSAN – Catalyst System Efficiency Below Threshold Bank 1
P0430 NISSAN – Catalyst System Efficiency Below Threshold Bank 2
You can eliminate the codes by using a spark plug non-fouler which tricks your engine computer to think that everything is working fine. This simple trick will pull the O2 sensor away from the exhaust flow and the computer will think the Catalytic converter is working properly. This will work if you remove the catalytic converter or have a bad cat. It’s very simple and cheap to do. Below is a video on how to perform the fix:
You can also buy them pre-made on eBay if you do not want to drill.
Make Your Own Spacers/Foulers
You can buy these non-fouler spacers at your local parts store. You can get them from Advanced Auto or Autozone for about $7-8 bucks.
You now need to drill out 1 of the non-foulers using a 1/2″ drill bit. When finished this is what it will look like.

Below are photos of the spacers installed and 100% working on Nissan Maximas by generation. After installing the spacers, the CEL codes went away.
