I don't think the install is a big issue, the underhood mods shouldn't mess with any important functions. They may just have to move a few things around. Then it's just drilling the holes and mounting. I've never had work done by 4wph's but have heard some bad stuff so maybe you may want to just buy the snorkle and give it to him in the box and let him worry with the install. Or find an independent 4x4 shop, your local mechanic shop or even a body-shop since all of the work involved is non-mechanical work.
