Arai TDF3 Duct Set 4.2 5 5 5
Cheaper than a new helmet The Arai TDF3 duct set is OEM, so fit is no problem. The ducts on the Arai are notorious for their fragility; some would call them cheap icing on an expensive cake. But Revzilla doesn't charge an arm and a leg for them, so we move on. Remember to clean your helmet shell well before installing and position them carefully, the two-sided tape only sticks well once! And, oh, don't let your helmet roll off your bike seat! These duct openers are FRAGILE! April 27, 2016
Got what I paid for, but it never should have broken. Bought these replacement air vents for my Arai RXQ. They are what I expected and work well after installation. The originals broke after owning my helmet for 3 years for no particular reason. I pressed the plastic button one day while riding and it snapped in half, which is unacceptable for a $600+ top tier helmet. Arai needs to redesign these vents or reinforce the plastic buttons.

didn't know these could be replaced I have a Signet-Q helmet and the smoked version matched the old ducts perfectly. 4 stars since I'm a bit miffed that on such an expensive helmet I had to replace it at all. One of the vents no longer "clicked" into place. Just sort of flopped around. The only question I had was how do I remove the old duct? Easy... put your finger under the front opening and give it a good yank. It will pop off. Then just clean the area and stick the new one on. Pretty easy... just make sure you line it up right before you stick it. July 17, 2015
EASY PEAZY RREPLACEMENT I only gave a 4 star because the only color you can get is smoke. Cheaper than getting it from Arai themselves though. Easy to replace. Thanks Revzilla!! January 19, 2015
E-Z replacement I gave 4 stars because my helmet is the pearlescent white and the only replacement parts in stock were smoke colored. I would've preferred the vents to match my helmet's color. Otherwise, removal of the old vents and installation of the new ones was so easy that I did it during a commercial break while watching TV. The package holding the vents is smaller than and iPad, maybe the size of a Kindle. The box they came in could've held at least 2 dozen. A padded envelope would've done better. September 2, 2014
