Front vs. Rear Air Intake?
I've got a Riva 4" rear intake on the way, and have been reading up on the install as I wait for it to arrive.
In my reading, I came across this article on the Fizzle site:
The part that's worrying me is:
"The rear air intake is by far the best performer of the bunch but it is only for flat water riders as water ingestion becomes a concern with wave jumping or anything else where the rear of the ski tends to get partially submerged."
I ride almost exclusively on a river/lake, and I love to jump over boat wakes, but it's rare that I get water up to the rear of my seat. Should I be concerned?

I have run rear air for years and never had an issue ...
But if u jump big and the back sinks too deep then u may get water injestion ...

and he hinted that some owners run other filter material in their rear intakes. Anyone got info on what other options are out there for filter material?

RXPJAY: Nice - Did you make any hull mods to get more air to the rear?

Not yet. Planning on something to move cooler outside air from the front through the hull. I know it's probably pulling a little warmer air back there but have not seen a boost drop. Did back to back test with the 4" front air as i was down 200 rpm since the spring in the summer heat and got them back with this set up. i guess with less restriction and shorter distance. I order a 4" adapter from jlewis and going to try this next.

Any filter you run--weather the filter RIVA provides with their RXP rear air kit or one like RXPJAY has you will lose 80 to 100 RPM. I have done many tests on these thru the years. I have never had any water injestion--of course I do not do 180s and 360s. You should be OK.
