So I just bought this exact turbo blanket from the Gotham Racing group buy for my T04S. You can see those two thingies in the front that apparently are used to fasten it... but what should I use to hold them together? A zip tie is not going to work, and they didn't include anything else with the blanket.

 

Use some safety wire.

 

they make metal zip ties

 

I just used some wire like Turbo II Rotor said and I haven't had it come apart so far.

 

I always just lay the bastards on and tuck the edges between the frame rail and the LIM and call it a day. No use in making it harder to work on than it has to be...you will need to take it back off one day.
