IMCO Power Flow Plus Manifolds
 

What does everyone tihink of IMCO Power Flow Plus Manifolds?

I'm thinking about putting them on my HP 500s, amoung other upgrades I'm going to do to the 500's?
And also, who has the best $$ on them?
Thanks,

Teague says they work great. The only problems I have heard is they have a wet joint between the manifold and riser, so potential problems down the road. Most have the small jumper hose so the joint is dry. Go CMI.

I have had mine for years and work fine. I have never replaced the riser gasket. I never seperate them because they weigh very little compared to the cast iron.

Is anyone using the Power Flow PLUS manifolds?
Thanks,
Dean

5+ years

Never a problem with mine either in 6+ years

Had them on my old boat . 5 years no problems

Sounds great guys, any ideas on who has the best $$ on them? I've looked on Ebay, and of course here in OSO, but no luck.
Thanks,
Dean

I used them on mine, no problem 7+ years.

Just sold mine. In my opinion they are a very good manifold. Not a header mind you, but good none the less!!
