I have an Alta AMP-INT-435RD = JCW, Red intake tube for TRADE for a aftermarket NON JCW R56 N14 S engine. I picked this up and didn't realize its a tad bigger than the non JCW one. In excellent condition, this retails for $248.40.

 

How good is it? Is it the best intake boot for jcw? Is it better than silicone?

 

Its not a boot, its mandrel bent powder coated aluminum. Superior to silicone

 

thanks going to install it tomorrow.
