A straight 6 Air box / filter question!

Post by Joe. » Sun Jan 20, 2019 6:34 pm

I recently bought an origonal Reliant air box for my Straight 6. Just wondering if anyone has got a picture of how exactly it should mount on to the carbs? Is it just held on by the base of the air filter or is there a metal / rubber adaptor to bolt on?

Heres a couple of pics:

Also has anyone got any suggestions for which AC air filters would fit? I see you can buy some of a similar pattern...

The filters you want are AC A2435 which cross references to these

I'll grab some photos of how the box is mounted, but you're missing some aluminium mounting plates and steel brackets. I think I have some spares somewhere though.

I've just had a look in my copy of the owners manual and strangely it doesnt show the air box at all! though I suppose they may have taken it off for the photos?

If you have some spare mounting plates I'd definately be interested in them, To use the air filter you've linked I'm guessing would also need to be used with a pressed steel lid?

Yes, I’ll grab photos of everything. I have a feeling that the first few cars didn’t have the airboxes and they were added after about 50 cars

Does anyone know if there's any advantage of running the airbox vs pancake style filters? My filters are up for renewal and I've always been tempted to drop the heavy airbox, mainly for aesthetics, but it could also provide better access to the carbs without taking the filters off.

Quite a few people ditched the original air box for pancake filters, though I've observed a resurgence to go back to originality.

Access is probably the biggest advantage to going pancakes, though you need to get the right ones to avoid restricting air flow (someone will correct me if thats not quite the right terminology)

The original filters inside the air box were wire mesh type, and to renew them they should be cleaned in petrol or the like. In other words, these don't need to be replaced. I suppose a paper filter type could be fitted - if you can get the right size - and this obviously doesn't last forever.
