acaie Posted July 7, 2021 Report Share Posted July 7, 2021 I'm looking at replacing the K&N air filters on my Grinnall which has a standard 3.5 SD1 engine. I've tried the K&N web site and can't seem to find the right one. Does anyone know the part number? Can anyone suggest an alternative? Al Quote Link to post Share on other sites
TR8IAN Posted July 8, 2021 Report Share Posted July 8, 2021 Hi Al, are you looking for K&N filters which fit in the original TR8 air boxes? - if so I'll look at mine and come back to you. regards Ian Quote Link to post Share on other sites

TR8IAN Posted July 12, 2021 Report Share Posted July 12, 2021 Here we go: https://www.knfilters.co.uk/air-filters/triumph/tr8 they are quite expensive though, you might be able to get them cheaper elsewhere. Will your ones not wash out? Cheers Ian Quote Link to post Share on other sites
