euan douglas Posted January 26, 2017 Report Share Posted January 26, 2017 Looking for advice and thoughts please. My GT6 currently has K&N pancake filters, which were on the car when I bought it. In the interests of originality I have got a standard air filter box which I'd like to fit, so I have some questions: 1. Will fitting this make any difference to the performance/running of the car, if I change nothing else? I have no idea what needles are fitted or if they are even different from standard. The car runs/idles perfectly. 2. Is it better to stick with the K&Ns? 3. How do the inlet hoses for the filter box attach to the side of the radiator, or do they attach elsewhere or anywhere for that matter? Thanks for any help Euan 1 Link to comment Share on other sites More sharing options...
dougbgt6 Posted January 26, 2017 Report Share Posted January 26, 2017 Original box good, K&Ns pretty, but not so good. The standard box allows colder air from the front grill into the carbs via the hoses. The K&Ns take in the hot air that surrounds the engine which may prove troublesome in hot weather or warmer climate. My hoses used to be held in place by a wire clip which attached to the front of the chassis. This has long since dropped off and the hoses now screw into two holes in the cardboard radiator cowl surround. I believe this was the previous standard and the wire clip a development too far. No change in needle or set up required. You can just make out the cowling holes here: http://www.canleyclassics.com/triumph-gt6-mkiii-radiator/ Link to comment Share on other sites More sharing options...
Waynebaby Posted January 26, 2017 Report Share Posted January 26, 2017 I made the same swap last year and noticed no change in performance. The car is quieter as well as being happier in stationary traffic for the reasons described by Doug. The air filter hoses I got from Rimmers were fractionally too short to allow me to put them through the radiator cowl and so I ended up attaching them to the outside of the cowl with self-adhesive cable tie fasteners from Maplins. They're not in front of the radiator but they get the benefit of drawing air from a cooler location than before. Wayne Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 26, 2017 Report Share Posted January 26, 2017 Cheap hoses with smooth inside get from aquatics pond pump, hose or 1.5" plastic waste pipe but this needs a cut and glue to get the alignment pete Link to comment Share on other sites More sharing options...
68vitesse Posted January 26, 2017 Report Share Posted January 26, 2017 Reading the above is there any advantage fitting air filter hoses to the MK1 2L Vitesse?, I believe the MK2 had them as standard. Regards Paul Link to comment Share on other sites More sharing options...
Clive Posted January 26, 2017 Report Share Posted January 26, 2017 If you can get hoses to draw air from in front ofthe rad (Ha ha ha) or at least next to it so cold air is drawn in, then yes. And I would agree with Pete, smooth bore hoses are a very good idea. Link to comment Share on other sites More sharing options...
euan douglas Posted January 26, 2017 Author Report Share Posted January 26, 2017 Thanks for the thoughts. Just as I had hoped - no change to the setup required and in fact a positive benefit from drawing in cooler air, so win-win all round. I see Canleys do the hoses, I wonder if they might be longer than those from Rimmers? Euan Link to comment Share on other sites More sharing options...
euan douglas Posted January 26, 2017 Author Report Share Posted January 26, 2017 PS I don't have a radiator cowling so I wonder if that would be a good investment? Euan Link to comment Share on other sites More sharing options...
Clive Posted January 26, 2017 Report Share Posted January 26, 2017 Yes, it helps to keep the engine cool. Not difficult to make at home with sheet ali, though no idea how much they are to buy. Originals are millboard (stuff that is a cross between cardboard and hardboard) so ali is better. Well, in my opinion! Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 26, 2017 Report Share Posted January 26, 2017 Go to garden centre or pond aquatic centre , you can buy metres of it for the price of the car spare emporious 1.5" is the size plus a couple of hose clips. Even the best triumph achieved was a rather cheap W style support on the sode of the rad frame and every 6 pot had the hoses as std. From day one .

dougbgt6 Posted January 26, 2017 Report Share Posted January 26, 2017 Euan, the radiator cowling and engine side panels are an excellent way to keep the engine temperature down, that's why Triumph put them there! The front cowling ALWAYS sags, why is that!!? You can get Au ones but I've reinforced mine with strips of wood, underneath, out of sight. Link to comment Share on other sites More sharing options...

Paul H Posted January 27, 2017 Report Share Posted January 27, 2017 Hi been following this post with interest. See attached pic - is this Hoover tube inner considered smooth ? as would like to fit on my Vitesse mk2 Air Box - only issue is will the missus miss a much shorter tube ? Best regards Paul Link to comment Share on other sites More sharing options...
Clive Posted January 27, 2017 Report Share Posted January 27, 2017 Nope,still bumpy! Rubber radiator hose should work.1 1/4" or 32mm ID (from memory!!!) Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 27, 2017 Report Share Posted January 27, 2017 When I get on the laptop (its piped up in the conservatory... Brrr) I will post a pic of my waste pipe version , if you want something to make up clives idea of straight rad hose is good , but I reckon 6cly vitesse is 1.5" same as my 2000 4 cyl in probably smaller Measure the spout ? pete Link to comment Share on other sites More sharing options...
Paul H Posted January 27, 2017 Report Share Posted January 27, 2017 Hi Pete , Clive is correct 32mm . Would appreciate a pic of waste pipe conversion Best regards Paul Link to comment Share on other sites More sharing options...
Clive Posted January 28, 2017 Report Share Posted January 28, 2017 That is down to my sad knowledge of vacuum cleaner hoses! (actually used a section of stainless hoover tube as radiator hose joiners) Link to comment Share on other sites More sharing options...
dougbgt6 Posted January 28, 2017 Report Share Posted January 28, 2017 Thanks for the advise Pete, but I find the dongle works best dangling out a South facing window. Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 28, 2017 Report Share Posted January 28, 2017 this is whats made up from 1.5" plastic waste pipe flared the ends with a hot air gun and a suitable socket glue welded the joints the cross tube was just a support , , slot the ends to get the hose clip to clamp up ok.

Amphletize Posted February 1, 2018 Report Share Posted February 1, 2018 Out of curiosity on this subject, is there any advantage to having K&N style filters with an air guide to direct cold air from the front of the car but without an enclosure around the filters? I prefer the idea of an open filter that has less restriction on the amount of air it can suck in, if that makes sense? Simon Link to comment Share on other sites More sharing options...
