SLP runner question
I am thinking of buying a set of SLP runners for a 89 Tpi setup. I am running a 87 Tpi setup and was wondering will these fit my setup. Thanks for any info.

Re: SLP runner question
IIRC 85-88 has the cold start valve hole, and 89-92 doesn't!! That should be the determining factor!!
As for your particular set up, they won't work, if they were 88's, then yes, you would be good to go!!
This info is from slponline.com

Re: SLP runner question
You will have to plug up the cold start portion. Not a big deal but needs to be done for use with the later TPI systems other wise you will have a big air leak.
