Excellent news. I wonder how similar the seals actually are to GM ones. Looks like CED had a kit of four for $37. VW/Audi kit for ONE injector from ECSTuning is $22.

A friend with a MK6 Golf R mentioned they were an upgrade for him. I'm unsure of their applicability to the 3.0T; pretty sure we use larger injectors - but it's nearly impossible to find info on how much they flow, I've tried a handful of times. There really doesn't seem to be a lot of "ingenuity" in the Audi S4/S5 world - more follow the leader, so it's hard to get real good info sometimes. Everyone just upgrades the HPFP. I've read that our biggest limitation is actually the low pressure stuff. Stock fuel pump is like a 450 gph or something like that, but the bucket is designed poorly, so at low pressures, it actually kind of struggles? Been a little while since I read the thread, but I seem to recall that being accurate.

 

I'd honestly be surprised if the injectors are much larger if larger at all, since the individual cylinders are the same size as the tfsi. I dont know what the power differences are to see how much fuel they would spray per cylinder.

 

That's a good point. The part numbers definitely aren't the same and the injectors are definitely physically different. Also looks like VW/Audi injector seals kits for the MK7 GTI are similarly priced to the GM ones. Damn Audi tax.

I'll have to do some research. I think I might actually have a rail with LNF injectors in my garage... but I also might have sent/sold them to someone on here before. Pretty sure they were in Colorado, actually.

 

I have a rail and injectors that I just removed to install opels that I could sell to you for a reasonable price (they have ~140k on them)
