Here is the link to what I purchased and it works perfectly:

I still don't quite understand how the Bo system is set up on our cars.

Do they have a factory bov that can be replaced with an after market on the will achieve desired results?

Going through all the post it looks like one by intake manifold and then that latest pic of that thing on opposite side of the front valve cover (that you put the filter on)

Two electronic valves on the charge pipe from the rear turbo. Technically they should be called a "bypass" valve jf they are routing the air back into the intake. There really isn't any room for one on the charge pipe from the front turbo so I'm sure that is the reason for 2. One closest to the rear turbo and one closer to the intercooler( and front turbo). Both vent back into the intake pipe. Since this car doesn't have a MAF sensor it doesn't matter what happens to the air from these valves.

There is no reason to put a filter on the ends of the factory valves or any. A blow off valve should have zero restriction and obviously does not need filtered. This is about as dumb as putting air filters on your exhaust tips. Think about it.

You have 2 options for change.

- Stock valves, vented to atmosphere. Capping off the intake pipe. Now you can call it a "blow off" valve.

- Ecoboost power parts hot (charge) pipes and an aftermarket mechanical blow off valve.

It would be nice to see someone make a direct replacement mechanical non plastic valves for the factory charge pipe. Would need to come up with some sort of a plug to go into the factory bypass valve harness to trick the car into thinking they are still there. I'm going to look into making something like this is LMS can't "turn off" the factory valves with the tune.

^^^With the amount of road salt and sand used around my parts, there is no way I would leave any opening to the air flow into my engine and therefore I introduced the filter. Especially since I have no means to confirm that the factory BOV does not introduce any vacuum.

Better safe than sorry and it wont hurt anything and probably LOOKS cool !

The won't hurt anything is not confirmed as your restricting the air being released, meaning all the air is not being release the same as without a filter.

Without have the tools or formulas to calculate or measure it, I am not sure that the filter itself creates any more friction loss than the original setup that has a short section of tubing going into a t-shape convergence of air flows. One thing I am sure of is that I will not get any debris vacuumed through the BOV with a filter.

Many thanks to Chuck for the red caps. With the front cover, and the red battery terminal cover, it's just the right little splash of color to go with the Typhoon's filter. But the big deal was, it prodded me to get that back hose off the rear BOV. Take the BOV off with the two bolts (I think it was 8mm-long), use a small screwdriver to spin the clamp around to where you can get a pair of pliers on it and ..... Presto! It's off!

Yes thank you chuck! Received my caps today.

I still have a few left over.

I'm out of town for work, return the 5th, if you aren't in a hurry PM me and we can work something out.

Josephm · February 25, 2014, 01:24:45 AM

I just got mine today as well so I have extras if anyone is interested

I was asked recently, where I purchased my silicone end caps from, when upgrading to the new hard, hot pipes.

Well, here's the link:

http://pages.ebay.com/link/?nav=item.view&id=330725834159

You can order any size diameter desired, but 25mm is what I got.

They come with clamps, & your choice of red, blue, or black.

Come two, per order.

I too, albeit temporarily, used some of the alternative options listed previously (discussed within this thread) but was concerned about longevity in the engine compartment.

The product I listed, resolved those concerns for me.

Hope it's of some help to those looking / needing such items.

Yes, I did check Samco Silicone hoses 1st, but they were nearly double in price, at only one piece per order.

Heck with that!

Carry on good people.

My only concern is turbo spool. I've don't the conversion but doesn't the recirculation force air and keep the turbos spooling whereas now it has to gather only air from the outside

Kolk1 · February 25, 2014, 11:41:30 AM

I did this mod yesterday, and normal driving, I never hear it. If I try and act like my car is a manual and snap my foot off the gas, I can barley hear it. If I roll the window down, and turn the stereo off, its "ok".

I think it must be a comparison gap, when people say they can hear the turbo spool due to an intake on these cars, or how loud the stock BOVs are, I don't think you guys have owned a car with a bigger turbo. My last car was a 2010 Genesis Coupe turbo, that I did a big turbo on, bigger fuel system, and the works, and that turbo you hear spooling up over a loud stereo with the windows up, and the BOV could be heard for blocks away.

I think im just going to take my caps off, and return the car to stock. Since I didn't even hear the BOVs once on my 45 minute trip to work, I don't see the point.
