Does the flow thru 507 work good, or do they take air really slow? I have the 507 that you remove on the truck but they sent the wrong ones for the fiver.

To CumminsDriver, I have had them for four years with absolutely no regrets. Just make sure that you have metal valve stems. For the rest of this post, I do not have flow thrus but am interested in others experiences. Thanks for the op asking the original question.
