TPI Runner bolts
Anyone know what size or where I can get the bolts that attach the runners to the plenum and intake?? I'm getting a TPI setup that's missing these bolts so I need to get some.
Thanx in advance.

Check a fastener supply place - they are metric, so take one of each length to properly match them. I think there are three different lengths, but I'm relying on memory (scary). Some of them thread thru the intake (not blind holes) so you could go a little longer at these particular locations. All of the runner-to-plenum bolts thread thru (I think - memory again).
Get socket head cap screws and a long ball-end allen wrench. These came with my SLP runners and they are the only way to fly. The ball-end allen allows for a pretty drastic angular engagement (like a socket swivel), which makes the bolts much easier to get to. I also replaced the TB bolts with socket head screws to get a consistent look.

The Runner Bolts are M8 with a 1.25 mm Pitch, and lengths vary depending on the application.

Re: TPI Runner bolts
I replaced all of mine with black allen head ones from Lowe's. It's been a year since I did it, and I don't remember the exact lengths I got. I do remember needing at least 2 different lengths though, seems like the inner runner-to-plenum bolts are a little longer if I remember correctly. You can also pick up a bolt set fairly cheap off ebay:

Re: TPI Runner bolts
All the runner bolts are M8 x 1.25. You'll need three different lengths: 30mm, 45mm and 80mm. Sorry, but I don't have a count of how many of what length you'll need.
I'd recommend 18-8 stainless over black oxide. The black oxide ones will rust and they'll look pretty bad.
I bought the 30mm ones in a pack of 25. The 45mm and 80mm came in a pack of 10 each.
In general, beware of cheap bolt kits. Cheap stainless steel bolts are pretty soft and will twist apart pretty easily.
