Anyone have an idea? What does it cost? Thanks, John.

Locally I dont know... but RRE does cleaning I beleive. Thats where I got my 450s exchanged for cleaned ones for 20 bucks.

Each or $20 for the set of 4?

You pay 80 for a set and then you send your old ones back and they refund you 60 back. Good deal. Comes witha flow chart. But that was for 450s so Im not sure if they do them in house or what.

Check out TPIS, they do a lot of injector work.
