Keeping your Honda Civic running perfectly for daily driving and track days is of paramount importance. With all the souped up parts you installed, a rough performance followed by emission of black smoke are tell-tale signs that something is wrong with your engine. If these symptoms start manifesting, it can cause you a default on track day. You wouldn't want that to happen, right? In order to prevent such situations from making a surprise appearance on your way to the track, you have to make sure you have an equally capable fuel pressure regulator to match your performance parts. This is why aftermarket tuning brands like AEM manufacture quality parts to ensure that when the V-tec kicks in, you will be grinning all the way. And an essential component of the fuel pressure regulator kit is the AEM fuel pressure regulator O ring. We took a look at how the entire ensemble could help keep our modified Honda Civic perform at its best. During the time of our test, the Civic was already manifesting signs that its old fuel pressure regulator was due for replacement. Here's what we found out about the kit containing the O ring:
- CNC-machined from 6061-T6 billet aluminum
- Directly compatible to both original equipment fuel rail and AEM High Volume Fuel Rail
- Interchangeable discharge orifices that match the output of your fuel pump
- Adjustable within the following range: 20 psi to maximum fuel pump capacity
- Manufactured in the USA
- AEM provided a clear step-by-step instruction manual for the installation of the fuel pressure regulator. It included an itemized list of the components included in the package, torque specifications, and a blown-up diagram of the kit.
- After the installation, our Honda Civic was as healthy as a horse again. Idle remained at constant below 1,000 rpm without hints that it would stall. Eliminating that hesitant behavior of our Civic gave us a more assuring feeling. The black smoke coming out of its exhaust was also gone by the time we installed the AEM fuel pressure regulator.
- Unfortunately, this component is legal in California for race cars only. If you are using it on your daily driver, better make sure that you are driving it outside that state. Fortunately for us, our weekend warrior Civic is driven around Nevada.
The AEM fuel pressure regulator kit restored the performance and response back to our Honda Civic again. Installing it to your Honda can provide the same benefits as well. Just keep in mind that this kit can only be used in California if you are driving on the track.
