Vauxhall Viva HA and maybe Viva HB
1568 Paper Air Filter Vauxhall Vauxhall Viva GUD AG 529
I've seen this data in quite a few spares lists Robert, but I really don't think it's correct... The HA Viva had a round 'pancake' style filter and, obviously, that won't fit the Hesketh. There are a zillion photo of the early Viva
here and every one that shows the filter assy, shows it to be round...
The Chevette filter is a rectangular panel, but it's about 30% too long for the V1000 filter boxes...
Chevette Panel Filter Dimensions:Height 0.938 in (24 mm)
Outside Length 11.844 in (301 mm)
Outside Width 3.50 in (89 mm)
V1000 Panel Filter Dimensions:Height 1.00 in (25.4 mm)
Outside Length 9.00 in (228 mm)
Outside Width 3.50 in (89 mm)
A K&N re-usable filter for the Chevette is still available (
Pt. No. 33-2502) But it would need to be 'cut and shut' to fit and I doubt that would do much for the 're-usability' of the product...
I'm planning to fabricate a couple of alloy/mesh 'frames' to sit in the OE air filter boxes and then fit 'Ramair' re-usable filter media into those frames... It'll be a sort of 'bespoke K&N' that will allow me to keep the OE filter boxes...
Hope that helps
