Outer Limits 4x4 Board

Ey guys was thinking other day of fitting a gq deisel airfilter into my mq deisel instead of having the two at the moment is it worth it or just to stick with the two normal ones?
cheers benny

GQ diesels originally have two also, it just most poeple ditch one of em, I only used one on both my MQ (SD33) and GQ (TD42), just kept the engine one and disconnected other ont, if that makes sense.
