Many of us are using it. I have had mine installed for more than 2 years. Works good. No longer any chance of the Air Duct collapsing at WOT. Mark made a great product!

Thanks Guys for the endorsements. Doug

If you want one one year old that is perfect I will cut you a deal. I just got the samco hoses so I don't need it (like the look)

the coplon duct is really nice and not only prevents the collapse, it smooths out the airflow and is very affordable and well made.

mark did stop doing the airblaster I think because of the amount of work.

has anyone bought a duct recently? marc is selling his zr1 by the way, super nice car.

Do you have the metal insert or is it inlet with the metal insert in it?
How much are you asking for which ever one it is?
