These arrived this morning, so I'll get them fitted at the weekend and see what I think. They're the stock airbox inlet rubbers from a 2010 V-Strom:

I fitted the DL stacks. It was straightforward apart from about 15 minutes of wiggling, tugging and twisting to get them mounted properly: I inserted them up and through from the underside of the airbox. A trace of red rubber grease and a bit of swearing helped.

I did about 250 miles over the weekend, and the difference is noticeable. The throttle response and pick-up in the 3,000 - 7,500rpm is sharper and stronger, especially in the first half of the twistgrip movement. A couple of times I was behind cars that were travelling at a steady 65 - 70, cruising on a light throttle, and when I gave it a little tweak of the grip to overtake being sure I must be in 5th because of the ease which I punched past them ... only to find I was actually in 6th all along.

They suit my riding style, as I hardly ever go over 8,500/9,000rpm and very rarely use more than half throttle (the bike is standard with standard gearing etc apart from a SV1000 airbox snorkel and the new stacks).

They're definitely staying in.
