barbagris, interestingly those "restrictive" filters socks from UNI-Filter actually make more power than the RAMAIR on my dyno. I find that flow testing filters is not the same as putting them on an engine. Relating to all the above posts, I note how folk are quick to hang shyte on the supplier within minutes, every one has a bad day or bad batch,whatever. I've had allsorts over the years. Surely how they respond to a problem is important? If they sent a new one out thats good. I had trouble with the RAMAIR coming off, with the first time I fitted one. Not since then, after I worked out how to do it, have fitted about 8 to 10 I think now. I tend to agree, they should have a rib inside the rubber to match the stock TB, although no K&N's etc have. I did send them a email to that effect. I have not ripped one yet, the rubbers seem quite good, so maybe gibbon had a dodgy one. Also interesting Scott/Warp, that you are putting another turn into the inlet tract with the above adaptor, but don't like them in the exhaust
. Hows the shoulder doing? Having the op soon? Happy New Year.
