I got the original air box beautifully powder coated and then, in a bottom drawer of the garage, I stumbled upon a spare conical K&N filter dating from my MGB days. Hmm I thoiught, and what if…
Yes, it fits perfectly to the spacers on the HIF carburetors. I mean perfectly in tne context on 70s British engineering, ie, of course there is a gap between the 2 parts that the stock Jaguar paper gasket would not be able to deal with (same gap with the restored OEM air box…).
The exhaust manifold will be replaced with a set of ceramic coated header, and the mufflers will liklely be deleted (resonators will stay). May be a little more breathing-in will help. But how to get fresh air to these K&N? Hood louvres, wheel well side gills à la Aston Martin?.. The madness never stops does it…?
(I build and race vintage 4 strokes dirt bikes and I know the phenomenal change when we open an airbox and exhaust…)
So I wonder: get another K&N or stick to stock?
