At first blush, that price seems high. But we'll need more details to be certain.

An IMS / clutch / flywheel upgrade is generally $3K. But there are a range of IMS options available and priced differently - from replacements that last a certain # of miles to ones that are a permanent replacement. So it's important to know which IMS is included in your est to determine if the overall price is in the ballpark or not.

Replacing spark plug seals isn't difficult or particularly labor intensive, so that shouldn't be a budget buster.

"A few other minor replacement parts" is too vague. Porsche parts are by nature expensive, but no way to judge an est based on replacing a few parts. Which ones?

Doing these items DOES add value to your car. The first question a prospective buyer will ask is if the IMS has been replaced. Not a deal breaker if it isn't, but the price will be discounted $3K if it hasn't.
