Snorkel (1 Viewer)

Hey folks! Can anyone tell me if this, although it is advertised for '80 and up FJ40s, would fit a '71?

I thought the body work from firewall forward was very similar in the upper fender area and the a-pillar?

If you have enough time and money you could make it work. First I would water proof the electrics including a radiator fan and move the axle housing breathers. Oh and drum brakes are nearly worthless when saturated, light brake pressure when fording will help, but stopping right after soaking is an adventure.

I agree it's worthless without a lot of work and silicone sealer under the hood if you cross anything deep. You'd also need to raise the vents on all your drive train parts to keep water out of those as well.

My purpose for adding a snorkel is actually simply to get cold air to the engine...I don't plan on any deep water crossings. I'm running a 427 Ford motor in the FJ, with a Wilson throttle body with a 5 and 1/8 in neck. Currently it has an aluminum 90° angle 4 in plenum that goes to a K&N oiled filter, but underhood temps even with the engine running at 185° can get well over 200° with header heat shedding. My concern about that particular snorkel or any snorkel in general is the restrictive nature of the diameter of the junction that goes into the fender...I think it might only be 3 in? Alternatively, there is a company out of Canada that makes fiberglass air filter boxes that look like the old ram air stuff you'd find on late '60s muscle cars. I could run a 17-in diameter filter box, with a 4-in snorkel coming off the passenger side, and then I could run a 4-in silicone hose to the louvered vent (with a 4-in flange adapter that I could affix to the inside of the louvered part) on the passenger side in lieu of a snorkel on the driver side. I'm just trying to figure out in my head if that louvered cross-sectional area on the passenger side would provide adequate air flow for the CFM my engine requires. Most engines like the air charge to be somewhere between 70 and 110° and drop off horsepower above that. If I ever did have to cross a stream somewhere, it would just be a quick matter of pulling off the silicon hose from the air cleaner assembly and just making sure no water goes above the height of the throttle body injector...and if it did, I'd have a lot more to worry about than just a wet motor.

I think with your setup, I’d repurpose the cowl vent and pull cool air from in front of the windshield.
