How many guys have installed these?

I found them only through dieselsite.com for the OBS .

I didnt see them on riff raffs site.

 

I've put them on a couple SD trucks, but no obs trucks.

 

i have a set for my 02, but have not put then in yet.
i got them from riffraff.

 

The Plenum inserts are on Riffraff's site:

He has a handy search function, I can't find glow plugs without using it.

Those are for a super duty 7.3 not the OBS. I tried searching there site it dosent look like he makes any for the OBS.
Thank you though.

I really wanted to see if this was a common mod done to the OBS. Every application ive read is just SD,s worried about over torqing there t bolt clamps and causing boost leaks.

 

Any particular reason, do you feel there unnessccesary for the OBS?

 

We don't make them for the OBS since you are already necked down, to reduce it further just lowers the flow. The Super Duty is large enough that they don't change the flow at all, but when we tested them on the OBS it was too significant of a difference to produce them.

 

Sweet thank you for the response.

 

I've never heard of (and never had happen myself) the intake crushing on the OBS like they do on the larger Super Duty.
Did you find the OBS to have the same issue?

 

Only if a t-bolt clamp is used. If you stick with the factory worm drive I haven't seen any issues since the OBS being smaller it lends itself to being more stout.
