    Default Cowling modification

    I have seen an EX-3 looking cowling on an EX. I will try and contact the owner to get the information but I thought I would throw it out here for thoughts. I am not sure if he modified the existing cowling or used a new one. Are the advantages worth the hassle and expense? Iím assuming the air flow/cooling is more efficient.

    Difficult to say if it will work as I do not know the EX-3 plenum, oil cooler, etc.,.. set up on the EX-3 compared to the EX. There could be interference issues and or fitment as the different engines may not have the same firewall to prop dimension.

    What I have seen on EX-2's are the shark gills cowl flaps of the FX/EX-3, X-Cub installed on an EX-2.

    My EX-2 runs pretty cold. The oil cooler and plenum do and excellent job. In winter I have everything taped closed and can get decent temps. In summer where afternoon DA's are pretty high, I still run normal temps. Except of course on hard climbs.

    I would call CC's and talk with them as they would know the correct answer.

    BTW, Sisters is a very beautiful place. Must be great flying around the area.

    Yeah, what I saw were the gills. I have an in-cockpit controlled oil cooler blocking plate that controls my oil temps. My curiosity is what the gills do for the CHTs in hot weather conditions.
    I do live in a nice area but youíre not hurting either. Lifeís good.

    I also did the oil cooler door mod. What a difference! Best engine modification to date.
