[Healeys] Denis Welch Foam Air Cleaners - BJ-8

[Roger Grace]

Of course there are many conflicting opinions like tyres and oil. My take is that the filtration capability is similar (or marginally better) than paper and that the ITG foam filters are more efficient (less restriction) and take longer to clog up.
The Denis Welch foam filters are made by ITG and a bit different to the K&N foam ones.

I would be very apprehensive about foam filters. First of all I would like to see proper evidence of filtration performance, particle size-air flow.
In first instance they could be suitable for racing purposes where bore/piston wear is not very important. Not many miles are driven that way and frequent rebuilds are in the cards.
For longevity of the engine I would opt for proven paper elements of renowned manufacturers or perhaps even K&N and similar, however particle size may be not as small/controlled as with top brand paper elements.
For looks: foam socks or K&N!

  Yes about a year ago.
  If you don’t mind the non standard look they are great. I don’t buy the extra 6HP that DW claims but no doubt there is less input air restriction compared to the pancakes.  A little noisier as you can hear the air flow  - I think that this is reassuring ! Well made and the clips work well.
  I bought the special oil spray they tout from ITG in CA as there are cautions about using the incorrect oil.
  An added benefit is that it takes but a few mins to remove the cover and get access to the SU pistons etc.

  Has anyone installed the Denis Welch foam air cleaner kit on a BJ-8?  



  If so, how do you like it?  What did you do regarding the breather tube that goes to the rear carb?
