I actually regret my Airflow Snorkel purchase. I don't mind the looks but the questions are ridiculous. "Can you go under water?" "Nice exhaust." Hasn't anyone seen Dante's Peak? Honostly, I did everything possible to make the plumbing water tight but with all of the seems and the rubber Ace hardware type hose that came with it, I just have no confidence to use it for a water crossing. I just lie to myself and tell myself I installed it to keep the dust out. For anyone looking to use this kit, use LOTS of RTV! I used blue Permatex. Also, if you are a 4cyl, you may need to cut a support bracket inside the fender. I opted to heat the 45 degree outlet with a heat gun and molded it around the bracket. The reduction in size will make no difference on a N/A 4cyl motor. I spoke with some one at Expeditioneers and asked why the plumbing was not fully molded polymer or silicone and I was told it was to keep cost down. I believe a piece of kit like a snorkel should not be cost driven. I'd pay the extra $100.00 for a something I have confidence in.
Sorry for the rant.
