My mechanic said I need to replace the manifolds, risers, and spark plugs on my 5.7 Gi-E engine. He said there is heavy rust do the risers "misting". The quote is around $1500. Does this seem like a fair price? Is this something I can do on my own? I have automotive mechanical experience. What about parts? I have looked around and found some places that sell each piece individually, but I wouldn't be sure what all to get. Does anyone sell an all-in-one kit? Any advice or input is greatly appreciated!!

The OEM cost for the manifold and risers is over $1300. If he is replacing with OEM it's a very fair price.

Thanks for the feedback! It looks like I'm just as well off letting them do it!

Is he using OEM parts, or using the cheapest aftermarket parts he can find?

I just called and checked - they said everything was OEM.

Its not that hard to do yourself but depends a lot on how much room there is to work around your engine. I only use the Volvo OEM manifolds and risers.

Ever look at stainless steel manifolds and risers?

No I never even heard of them. Seems like they would be a lot more expensive though.
