Tks all for feedback, awaiting Rick for the instruction manual

 

So it seems like this isnt a 15min job per stated huh?? DAMN! I dont have 7 hours to tinker with my car.

 

It took me about 45min with three tools.
Flat head screwdriver (used the type where you can change the tips)
5mm ball head allen wrench(used the empty screwdriver handle as a lever)
10mm socket (to pull out the over flow bottle for more space)
I never did unplug the wires from the BOV.

 

I think I spent around an hour doing mine. It was kind of a pain, but it didn't take too long.

 

When I swapped the BoV, the ball head allens were the lifesavers of the process.

 

Has anyone installed this spring in an auto trans?

 

Will this spring fit the aftermarket BOV??

 

This was designed for the OEM DV. I wouldn't.

 

I can confirm the spring for the stock BOV has nothing in common with the one from Forge for instance- but they are both springs.

 

The Forge BoV also includes 2 springs, so unsure you'd need a third for it.

 

Should I expect to get any performance benefits from installing this on an automatic trans?

 

Well, you guys convinced me! I just ordered the Oxspeed BOV spring for $10 + $5 shipping. After reading through all your tips here, I'm hoping the install goes smooth.

 

So stock with spring is better or Forge BOV itself is better??

 

I just installed the Oxspeed BOV spring today. It came with 3 pages of color instructions. The only odd thing about the instructions was they kept saying 'Torx' wrench. The bolts on my 2011 CMSA4 required an Allen, not a Torx wrench. However, you will need a Torx set to remove the air line.

I had bought a folding ball-end allen set for the job, but it was awful and only barely got the bolts out. Even with the air line out of the way there wasn't any room to use it. An L-shaped ball-end set would have been better, but this was all I could find at Home Depot and O'reilly's.

Popping the BOV valve off and installing the spring was easy, but getting the bolts back in with the folding tool was absolutely impossible. I grabbed my regular allen set and an extension for leverage (from my bike tool kit), and I was back in business. After that, I only had one more problem. A metal line above the BOV cover was preventing the top bolt from lining up, but I was able to bend the line slightly to make room. The short end of the allen had enough leverage to get the bolts started, but the extra leverage from my wrench extension helped finish the job.

I dropped the allen wrench a couple of times, but fished it back up with my magnetic screwdriver. The bottom bolt was easy. I thought the rear bolt would be hard, but putting a light on it helped me see what I was doing.

After it was all torqued down, I reattached the air line and double-checked my work. A short test drive later, and the improvement was noticeable. It's subtle, but the turbo really does spin up faster, which seems to make takeoffs easier.

For $15 shipped, this is a no-brainer.

Pre-install tips:
1. Either a ball-end or regular allen wrench will work fine. If you still want the ball-ended kind, get an L-shaped set.
2. You will need a Torx (star) wrench to move the air line.
3. Get an extension for the short end of the allen wrench.
4. Disconnect both ends of the air line and move it out of the way.
5. Test fit the allen wrench into the top bolt. If the metal line is in the way, slowly and gently bend it up a few millimeters until the wrench clears without rubbing.
