Plus the hose is too large at the TB end plus the Alta hose has no step inside which it needs to cancel the step on the TB rim.
We flow benched one against the (very similar) GTT Ram kit we do for the Renault a long long time ago. The GTT was around 15 -20% up on CFM . Take the GTT ram pipe off our kit and the flows very similar... The GTT Rampipe design makes all the difference. Our kit is available in a 'new' blue or black now at no extra cost. Red /Yellow etc £10+vat extra.
Best Regards Roland GTT

I got my Alta from the States before it came out in the UK and before Roland offered his GTT ram pipe, and Im very happy with it , you now can get a lid that fits on top (i think it must interfere with anyone who has a strut brace fitted , not too sure on that)
I suppose you have to try both to see which one you like (bit impractical and expensive) but considering Roland has tested both his advice has to me noted
If i need to get a new intuction kit i may try Rolands just to see the difference (thinking ahead for T350 kit he offers)
