Boyz, im just about to install Apexi dual chamber Bloff off valve on my 94 R33.

On the stock BOV - pictured below , what do you do with the big black tube that was attached to the STOCK BOV, as the new apexi bov only has the spot for the vaccume line ?

the big black tube is the "PLUMBACK" line.

sine the apexi is a atmo venting bov.. you simply block the big black plumback line.

take the rubber hose off the plumback line and put a coke bottle cap over the now open metal plumback line.

clamp it on there using the hose clamp off the rubber hose.

get me?

yep.

block off the rubber hose from the stock bov

leave that looped hose there.

the vacuum line from the stock bov goes to the top of the apexi one.

BEUTIFUL - thats simple enough. Block the black PLUMB BACK hose and take the vaccume line from the stock bov and connect it to the apex one.

The bov already has the flange adapter to bolt on as u can see. so it should be a 5 min install.

Thanks for your help man.

    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.

    • Wanna rewrite all of that in, say, 2 or 3 separate sentences, so that we can read it?
