Hi!
I have C6 ZR-1 and my intercooler pump just broke. When I tried to look for a replacement it turned that GM has discontinued making it. Nothing of such for sale where I live. What the frog am I supposed to do now? Can I order it abroad somehow? Do they deliver to England?

The pump is GM 15870574.

Thank you!

Used, but gets the job done.
Not sure if they can ship to you, but check it out.
Best of luck!!!

I believe there are additional options for the stock intercooler pump. The Stewart EMP, sold by Lingenfelter Performance Engineering is a solid replacement, at about 60% of the OEM pump's price.

Hope this helps....

absolutely time to upgrade. Consider Kong porting the blower too as anything you can do to improve the efficiency and keep the intake charge cooler is a big help.
