C63 Blow Off Valve Review

Sometimes all you are looking for is something to make your car unique. Something simple that can transform your car from an ordinary everyday vehicle bought off a lot into something that can turn heads and make people see that your car is different... Special even. Your not just an everyday driver, but a member of the elite, the cream of the crop, or even someone who got their hands on a one of a kind car. 

Sometimes you want to do that without breaking the bank or spending hours in shop tweaking your car. Lucky for us we have Turbos and even luckier we have the guys at turbokits.com turning out high quality parts for our cars without breaking the bank. 

Enter their Blow Off Valves. For those of you who are not familiar with what a blow off valve is or how it works I urge you take a quick read here  which will bring you up to speed on what blow off valves do for cars. The C63 comes standard with blow off valves that recirculate the excess boost pressure back into the system. What turbo kits have done is made an attachment that turns the standard system into an atmospheric system providing a unique sound that turns heads on the streets.


Turbo kits have a great website and amazing customer service that provide any assistance you may need when you need it. They offer a quick turn around time, once you have placed your order and come with all the tools needed to install the units.


Install on the C63 version is very easy. The instructions that were sent were very good, but here are some tips  Removing the 2 TORX screws will give you just enough room to wiggle everything around enough to get the parts out and then reinstalled.  Start with the driver’s side, it has no wires in the way so just some slight maneuvering and you can do that side in a couple of minutes as long as you DO NOT DROP THE SCREWS. With them being stainless(no magnetic picking up) and the plastic skid plate it will turn a 10 minute job into much more.   Once the screws are out and before you pull the bypass valve out make sure you note which way they are aligned.  Once the factory piece is out line up the holes and insert the new longer screws.  There is only one proper alignment as the 3 mounting holes are not spaced evenly.  Make sure to install it the same direction and tighten it down.


The passenger side is similar but you must first, remove the tape around the wire connector, unclip the grey safety clip(blue arrow) and remove the electrical connection.  This will allow you to move the wire away from your work area and get to the farthest left screw.  I also popped the silver clip (blue arrow) and got that wire out of the way as well.  After that just install just like the driver side.


So when we heard about these BOVs we thought we would try them out but didn't think we would keep them on mainly because it seemed like it would become an annoyance. Boy were we wrong after having them on for a little over a month these things definitely make a difference without making it annoying to drive with them on. Driving with even the lowest of music on and the windows up keeps you from hearing the BOV while driving, however, if you turn the music off you can hear the sweet sounds of the BOV's doing what they do best and venting into the atmosphere. If you roll the windows down it becomes even more noticeable and hearing it from the outside definitely has started turning heads and has people asking what have we done with the car.


These BOV's are definitely worth the money and will turn heads! They are easy to install and uninstall should you ever have problems with the car and need to take the car in for service. They offer no performance gains, but do not trip the Check Engine Light and they are loud enough to get other people noticing you without becoming an annoyance to drive with. We say if you're looking for a little extra something to get them!
