Is the stage two intake really worth it over the stage one for the 600 series motor. Also has anyone had any luck changing the color of these filters with the different color oils?

 

Couldnt tell you about the torque tube, but my yellow-gold pg7 is now k&n red,

 

Just get a stage one with the proguard 7 filter and the new cool blue hose stage 2 not worth the money. Look into the Scotty air systems there is a cool blue intake tube for the Ram air three as well

 

What's the difference between a Stage 2 (torque tube) and a Cool Blue Hose (which is about $50 MORE than the torque tube?

 

Where can i get this cool blue hose????

 

Check this out, I think it has all your looking for.

Bradleysram,

Can't actually say yet the Stage II's we have shipped are very few so far, the availability is VERY tight right now. The Stage I and a torque tube is NOT a Stage II intake system. The Stage II is a new part number 75-10812 that is for the most part totally different than a Stage I 75-10411 part number.
