Oh so fun>:D Acceleration is fantastic in this arctic chill.

Cannot wait to get my blowoff valve spacer installed Monday!


I'm starting to lose traction on hard accel, and the nanny controls are driving me nuts. Turning off ESP is crucial for 0-60 runs

Just a short clip, but it does sound nice. Are you going to post a picture of your own GLA accelerating with your new part installed?
That is 'my' GLA250 in the video ;)

Won't have time to install the Blowoff valve spacer until later this week :( But I will post a clip of that.

I questioned whether or not I should express an opinion on that spacer but since you haven't installed it yet I thought you may have time to rethink it. If I'm not mistaken and you may know better than me on this, the car has a bypass valve not a vent to air blow off valve. With this setup the ECU is anticipating that air to be part of the intake charge and since all of this occurs downstream of the MAF, it doesn't know that volume of air is being vented to air and not recirculated. With the other bolt-ons you've got, I'd hate to see you have a problem just for the fast & furious sound. Did Forge do a before and after Dyno? I'd be shocked if they actually showed it increased power.


Again, best of luck with it but I'd hate to see you have an unexpected problem.

First of all, our cars do not utilize a MAF sensor, so turbulence and flow is not an issue. The GLA250 has 2 (that I can see..) MAP sensors. Much different story.

Current turbo cars utilize a 'Diverter valve,' (recirculating system) that is regulated via the ECU, the 'Spacer' from Turbokits primarily increases the sound. The functionality of the part is cosmetic and fun.

I like the sound, if you do not, don't put it on yours.

If you need more info on this particular part visit: http://turbokits.com/Mercedes-Benz/CLA_250_-_C117/Blow_Off_Valves/TurboKits.com_Blow_Off_Valve_(BOV)_Spacer/2609/ they make them for the CLA250 platform and they are selling out of them as they get them in. Many people like a little talkback from their cars, not really a big deal. I find it amusing.

The spacer does IN-FACT reduce heat being pushed back to the intake side. (Though probably quite-marginally) So there is 'some' limited functionality

I also don't appreciate the 'fast and furious' comment. Please refrain. that's not what these forums are for.

As a moderator, I don't want to see this forum go down that road, we all come here to have fun, talk cars and save the insults for another time and place. I try out these parts and post them for the benefit of ANYONE who might come here with the intention to try out the mods I have.

how long do you think install will take on that BOV spacer?
Should only take about 10-15 minutes. I'm taking my GLA to figure out some issues with my LED headlight swap, so it'll get done that day and I'll be way out in an area to do some short 0-60 rips getting onto the interstate over there.

BOV spacer fit perfectly, easy install time of about 10 minutes. The upgrade is definitely more subtle than anticipated, which I like.

I'd say from the volume that my diverter valve made before was about a 4 out of 10 for volume with my intake installed. With the spacer added, I'd say it takes it to about a 5 out of 10.

If your windows are rolled up, you can hardly hear it at all. One caveat though: My intake makes the overall noise quite a bit louder than stock, so if you had stock exhaust and stock intake, the Spacer will probably be more noticeable.

I had time to make one pull, but the video turned out terrible, so I'll have to post another later. Sorry guys. :(

Also, I would not use the Turbokits youtube video to decide on the sound because sitting parked, and revving doesn't really show what it sounds like under load. It's quite different.

Just drove 35 miles, no issues, no CEL, just lots o' fun :)

Honestly no offense intended. I had hoped to just get across that combining bolt ons does come with a certain level of risk but it's clear you understand that. Best of luck with the car and forum. I'm out.
