Bravo Change Pollen / Cabin Filter

there are some small ridges on the top faces where the filter sits,
where the "fins" of the filter nestle..so it will stop the panel filter moving under airflow..
or indeed extreme driving

at this point I had an issue,
the Mk1 bravo filter was physically too big / oversize
for my 2001 Marea JTD - aircon equipped car
View attachment 180836
so I had to offer -up the original .
and against the 2 decided the WIDTH was OK , but just TOO LONG

so used a sharp craft knife to trim the filter down- I went fractionally TOO LONG.. then offered against the filter box frame, ALMOST fitted.. but the filter would not sit flat.. arched like a bridge

removed another 2 x segments from the filter - SUCCESS..!!

laid the filter into the filter box frame,
the ridges on the frame do a good job of locating the filter,
CAREFULLY stretch / work the 16 year old o-ring.. into place
