Regardless of the vehicle make and model the sucess rate is not guaranteed, there's no way for us to come up with enough data to confirm which model these will work or will not. Before you purchase you must consider the following , a proven solution is to flash the ECU with software when deleting cats or installing race headers however these 02 bungs may work , they worked great on Pre-2004 Porsche Models and other makes as well, and they didn't work well on other customer cars like 2005+ cars in some cases. This is a 50/50 if you can't risk it don't and move on to an ECU Flash.
Are you getting those annoying P0420 and P0430 Cat inefficiency malfunctions codes after installing cat-bypass pipes "Test Pipes" ? We may have a solution for you, this is not your usual O2 sensor spacer that pushes the O2 sensor away from the exhaust stream, this 02 sensor CEL fix actually uses a tri-metal substrate that is platinum/rhodium/palladium coating that works just like a real catalytic converter, this O2 Sensor Fix is to be used on the downstream 02 sensor (2nd O2 sensor). Made entirely of T304 Stainless Steel, these will not rust with time, once again a real metal substrate is used, this is a high quality O2 sensor fix.
Read extended description below.
Once installed the O2 sensor fix will come out by 37mm in length so you need to make sure that this can be installed on your application, in other words you need to check that you have enough clearance to install this O2 sensor fix. In addition please keep in mind that this will not fix a defective catalytic converter already in place or a bad O2 sensor. Installation is fairly simple simply remove your O2 sensor and install our O2 Sensor Fix and install the O2 sensor on the O2 Sensor Fix.
45 Degree Model $49.95 (Each)
This model will have your sensor at a 45 degree angle, sometimes the straight version won't work and the 90 won't work because the sensor may hit the cat if the cat is to close to the 02 bung that's when the 45 degree version comes in. The height is 2 1/4" or 60mm for the 02 bung alone remember to verify if you have room once you had your 02 sensor.
90 Degree Model $49.95 (Each)
This model is the 90 degree model, it also swivels 360 degrees, this is what you need for tight spaces when you don't have enough clearance to put a straight model "C.E.L Fix" . Once fully inserted inside the pipe the 90 Degree C.E.L Fix is 33m high and the length from left to right without the O2 sensor in place is 60mm so you need to make sure that this can be installed on your application, in other words you need to check that you have enough clearance to install this O2 sensor fix.
Look at the last two pictures, you can see a 90 degree model installed, due to the lack of room to install the straight model on a 997 turbo we had to use the 90 degree, the last 2 pictures are to show you what the 90 degree installation looks like.
About the success rate of our O2 Sensor Fix. For models up to 2004 It's important for you to understand that these normally work very well, there's a huge success rate but after selling hundreds of these we came to a conclusion that not all ECU's react the same , some ECU's are more sensitive then others and we have seen small failure rate approx. 5% reported negative results after a couple hundred miles. We don't guarantee that these will eliminate your O2 sensor related malfunction codes. For this reason there is no return on this item.
For 2005 + Models we don't have enough data but we have noticed that on 05+ models DFI engines the success rate is not as good, some customers did report back mentioning that the check engine light came back. We strongly recommend you purchase the larger O2 Bungs found here.
Important disclaimer These O2 Sensor fix are not street legal and should be used on off road vehicles, racing vehicles or for testing purposes only, these are not street legal.
About installation, the installation is pretty straight forward, these install on the downstream O2 sensor (2nd O2 sensor hole closest to the exit flange) , you must remove the O2 sensor, install the O2 sensor fix and lock the O2 sensor fix to your desired position and screw in the O2 sensor inside the O2 sensor fix.
