Hi, I've built an injected Pinto-based Cat E1. Now I'm trying to get some cool air for the intake. Going to the front, next to the radiator seems logical but how do I avoid water coming in when driving in rainy weather?

ducting loiw down with nmaybe some kind of upside down U-bend arrangement?

so air enters low, has to travel upwards, and then back down to the in-take, that way any wetness show hopefully travel up the ducct, then run back down again?

I wouldn't bother worrying. A little bit of water going into the engine isn't going to be a problem. If anything it'll just prevent pinking

After all, what to people do with sausage type filters that stick out of the bonnet and are fully exposed to our glorious weather???

You do need to be careful.

I had water ingestion in my engine during last Summers floods. I think it was due to my low intake arrangements. I was very lucky and my engine survived with just a new headgasket.

My engine runs fuel injection and a single throttle body. The air filter is mounted about 6" off the ground, just in front of the engine. It's fine 99% of the time but can be an issue if you suddenly find yourself wading through 12" of water.

I would mount the filter as high off the ground as possible. I would have thought a duct from inside the nosecone/next to the radiator would be fine.

If the water is that deep you've got bigger things to worry about - like floating away
