The second generation GT1R Flex Fuel kit is improved in both being completely plug and play to all year model R35 GTRs, as well as the sensor being relocated to the pressure side of the system.

The sensor on the pressure side of the system gives more consistent readings in the event that return fuel flow is minimal (if you’re nearly maxing out the fuel pumps).

We’ve also updated the wiring and now offer a plug and play wiring harness.  Like the rest of our wire harnesses, we use Race Spec, the best in the business.   Our harness is assembled using Mil Spec tefzel wire, Raychem DR-25 heat shrink, and new connectors for a durable and clean PNP installation.

The flex fuel converter box converts the digital signal from the ethanol sensor to a 0-5v signal that the stock ecu requires.   With this converter, the output is .5v for 0% ethanol and 4.5v for 100% ethanol.

There is no display used with this kit, as both Cobb and EcuTek allow the user to view ethanol content in their own ways.

The complete kit includes all plumbing, with high quality Redhorse Performance ethanol compatible hose and crimp hose ends, the ethanol content sensor and mount, and the PNP wiring harness.

We offer kits to suit the stock fuel rail, or aftermarket rails.  The stock fuel rail kit includes a rail adaptor to convert the rail inlet to AN threads.  If you’re using aftermarket rails, you will need to specify what size the rail is (6AN ORB or 8AN ORB).

Effective Cabin Air Filter – Fresh and Clean Air for My Car
I recently replaced my car’s cabin air filter with the AC85111 activated carbon filter, and I’ve noticed a clear improvement in air quality inside the vehicle. It helps keep the cabin air fresh, especially during daily commutes and long drives. The activated carbon layer does a good job of reducing dust, odors, and outside pollution, making the driving experience more comfortable. I also noticed less smell from traffic fumes and general road dust entering the car. The fit was perfect for my Honda Pilot, and installation was simple without needing any special tools. It is compatible with several Honda and Acura models, which makes it a reliable replacement option. The material feels well-made and sturdy enough for regular use, ensuring consistent airflow while filtering out impurities effectively. Considering its performance and durability, it also offers good value for money. Overall, this is a practical, easy-to-install, and reliable cabin air filter that helps maintain cleaner and fresher air inside the car.

Good fit for our Honda Accord, quality filter
This was the perfect fit for my daughter's Honda Accord. It's a solid, budget‑friendly upgrade that fits perfectly. It only took a few minutes to install. The pleated material feels sturdy, and the activated carbon layer helps cut down on odors and everyday cabin dust.

No more funky smell!
Have had a funky smell for a while in my car. Air fresheners just couldn't quite cover it up. I pulled the old filter out which was reallll caked up with stuff and got the new one in. Not only is the funky smell finally gone, but the HVAC is a lot quieter when on full blast, and it blows the air harder. It fit great, installation was easy, and having the smell gone makes it worth absolutely every penny.
