Air filter Volvo 700 (B23ET/FT/B200ET/B230ET/FT)

Sluggish throttle response, rough idle or noise from the intake on a turbocharged 740/760/780 can point to a clogged filter or a leaking air filter housing where the rubber caps and buffers have dried out. On the B23ET/FT and B200/B230ET/FT the filter sits in a housing that should seal tightly – cracked rubber parts let unfiltered air slip past the element and should be checked when changing the filter.
