    3" air to 4"

    Hey guys, i am already running the riva 3" air intake and i am wondering if you guys think it is a worth while upgrade, as in value for money in going to the 4" intake.. Also is it just as safe from water intrusion as the 3"?

    I run the 4"kanaflex with spectre filterfor a season now.
    Have been on big waves also without any issues,is the best flowing front air intake on the market,is as save as the riva but gives more performance gains.
    I woild say: go with the 4 incher.

    Yer from what i have read i would expect to pick up maybe 50-100 extra rpms going from the 3 to the 4"... You reckon this sounds about right? I have had a few probs with water ingestion going through rough seas with the 3" air though.. Nothing really serious, just a few splutters and stuffed up my plugs once

    The riva is under the seat,you must place the kanaflex under your glovecompartiment,place near the air intake hole,this way you have maximum airflow,but a dry place for mounting.
    Take a look at the pic that's where i placed mine,i took the glovebox out for easy mounting.
    Only thing you have to do is make a bracket or some guys use binders ,i prefer a bracket myself.
    I am sure it will give you more rpm's but depends on the climate in the colder areas you get more rpm's.

    THey mount wherever you want them to. The picture he showed is where most of us mount them. I have a friend who likes to nosedive my ski every now and then and when he does some water must get in to my filter somehow because it will cause my ski to bog for a few minutes.

    I dont do these so I have never had an issue.

    Agree it's 100 % safe,and mount the filter where ever you want it,as long it's near the air inlet your ok.

    I got my 4" from seadoo centre and have no water problems at all and we have been out riding when the cyclones are out off the coast to give us some big waves for jumping. I have made my own cold air intake thru the front storage bucket and still have no dramas with the water but it certainly lets the air in and makes that blower sound really stand out awesome.
