Terence Posted February 8 Report Share Posted February 8 There are two corrugated hoses taking the air to my air filter. What is their purpose as all it seems to do is take the air from the Left hand side rather than the right. One of my hoses had come unclipped and was dangling down near the road but luckily I had not been though any water or out in the rain. Should they be attached to a specific place? I am tempted to remove them, is this a good idea? Quote Link to post Share on other sites
Mike C Posted February 8 Report Share Posted February 8 The two things that look about the size of a vacuum cleaner hose? Mine have been gone for decades- as I see it they unnecessarily restrict the inlet air flow. Quote Link to post Share on other sites
michaelfinnis Posted February 8 Report Share Posted February 8 I don't have them fitted to my car (they weren't on it when I bought it), hasn't caused any problems that I've noticed. I did think about replacing them, but like you I can't see what purpose they serve. Quote Link to post Share on other sites
Terence Posted February 9 Author Report Share Posted February 9 Thank you both, I thought I must be missing something obvious as i thought they would not have put them there without a reason. Quote Link to post Share on other sites
Jonny TR6 Posted February 9 Report Share Posted February 9 Don’t they help reduce the hot air from the radiator going into the plenum ? Quote Link to post Share on other sites

PodOne Posted February 9 Report Share Posted February 9 I've fitted them because I had the material on hand but wondered why and directed them towards the holes in the lower valance. She's not for racing otherwise I'd bin the air filter and fit a K&N filer as it seems a restrictive arrangement. Andy Quote Link to post Share on other sites

I repositioned mine to have the horns facing the drivers side mudguard in the hope of picking up colder air with less pressure drop. Just looked at a Triumph 2.5 PI manual- the hoses are gone and the horns point down. Edited February 10 by Mike C Quote Link to post Share on other sites
