interesting. it looks to be more solid than the stock 4runner one which would reduce the amount of "stuff" that can get into it. I'm still curious if there are other options for reducing the chances of frying another alternator. I just bought a new one so I'm not really looking to buy another one right away lol. maybe when I've recovered a little bit from buying this last alternator and can find a reason to get the cs-144 without the wife asking questions lol
