A zed came to the workshop last week presenting some odd running problems, the ConZult was showing reasonable settings but if left ticking over slowly get slower and stall,the pick up was just not right and unstable, on a hunch I removed the elderly looking HKS mushroom air filter and once the afm was seperated it was clear the foam filter had started to break up and the afm air flow was getting blocked by the foam bits, a new filter and a clean out and all was good again, worth checking if you have one of these kits fitted.

I have one of them and put a new foam filter on it last year some time so must check it. Thanks for the heads up Jeff :thumbup1:

Wonder how long that had been on there without it being cleaned :sad:

No problem, prevention is always better than a cure as the saying goes!!

Do you remember Jeff the problem on my single turbo set up was the foam filter restricting airflow?

Yes that was right, can be difficult to identify it in any normal installations but yours was something else!! do you ever hear anything about it now?

never been keen on the foam ones.

Yes Cyberbean yours was definatly not in a good way , most of the foam had gone

Good info Jeff cheers I have one of these. Any ideas where I can get replacements

i had one on mine ,when it went to you jeff i got you to take it out and bin it

Is the Apexi still the recommended gauze filter? What do they cost?

My HKS filter was fitted by Zedworld many years ago one of the first things I did when I bought the SWB was change the foam filter and it needed changed.

 

Is the Apexi still the recommended gauze filter? What do they cost?

 

Yes it is Scott - if you can find one mate! They go for about £100.....

>> Is the Apexi still the recommended gauze filter?

 

A problem has been discovered with the Apexi ones as well...

They collapse under high boost...although rumors are this only happens with chinese copies which are sold as legit Apexi's and afaik can not be identified as copies.

 

example of what can happen:

 

On a near standard Zed this will probably not happen very easily, but for the bigger powered engines I'd go with K&N or JWT filters
