ASP new QEV (Quick Exhaust Valve) kit for the ION increases the gun's cycle speed by venting air right at the port rather than having to route the air back to the solenoid for venting the exhaust. Requires no cutting of the body for installation - it's entirely a 'drop in' mod.
The Air Soldier Products Ion QEV Kit is older, so while it may be available used and in a few cases new, it is not commonly available anymore.

None. Unscrewing is needed when disassembling, but not really a weekness.
I installed this fairly quickly after I got my Ion. The sound is a bit different when you shoot compared to a non qev ion. Stock, Ions kinda have a hiss, or a tsss noise when you shoot. After the QEV, it doesnt have that. Its just a quiet pop w/o the tssss.
Also the dwell can be lowered further than what was mentioned above. Every gun is different, but the avg high is not 15 blinks. Mine is at 10 blinks from the bottom, which translates to a 5.5 ms dwell. Stock is 52 blinks which is 16ms. Big difference in dwell setting. My inline pressure was also able to be lowered to about 140psi instead of the 170-180 stock.
Also, by putting the QEV in, it doesnt wear out the SFT oring any faster. The SFT oring just seals the chamber on the front of the bolt to make the breech a closed/sealed system when the air is released from the bolt. It does however wear out the bumper oring on the front of the bolt. Mine is the green oring. It is the oring that comes in contact with the bolt stop disc on the forward movement of the bolt. Since the QEV exhausts faster, allowing for quicker forward travel of the bolt, that bumper oring takes more of an impact than a normal stock setting. Its not much to be worried about though.
I have no complaints about the QEV. I think they should be stock w ALL ions, and they should include a spare bumper oring in the package. It wouldnt cost that much more.
All in all a great product for a cheap price. It does void the warranty though.
Recommended by me, easy to install, cheap, effective, and keeps grease outta the noid.

I was going to wait for SP's banjo-style qev but who knows when that's coming out. So i ordered the next best thing, Air Soldier's qev kit, complete with Clippard qev, quick-disconnect & a chubby little o-ring for the threads (so ya don't need teflon).
Installation is included on the back of the small packaging & is very easy. Only modification needed is trimming the pneumatic hose since the quick-disconnect makes the qev longer than the banjo fitting. Piece of cake, since they tell you how much you need to trim.
After installation, the dwell needs to be turned down. Another simple process. Those instructions aren't on the packaging but they can be found in the Ion Forum here (or just pm me). Mine is at 17, which is 2 clicks above the average high of 15, but it works so no complaints.
There's some concern about the increased cycling rate would wear out the o-ring in the front end of the breech faster than normal. But shooting at a high rof would do that, anyway, so i don't see why that's the qev's fault.
One of the cheapest upgrades available yet one of the most useful. Ions should just come with these.

When I got this I was amazed at what it did. I put it in my gun had a small leak so I put some teflon on it and and problem fixed. I lowered my dwell to zero and slowly raised it till it fired broke out the old crono I was shooting +/- 30 ao I raised my dwell a little more and there it was +/- 3 with 120 psi and maybe a pod and a half of paint out of a tank more.
:Edit: Oh ya one more thing if you have a ND trigger you are going to need to back out the pretravel screw a bit or you might break you switch.
Great product for the price and the performance that you get out of it.
