Intake Opinion

I am planning on getting a cold air intake for my 2003 F350 and am debating between either a Riff Raff or Tymar intake system. Does anyone have an opinion on these. I am not sure what the difference would be besides the price. I can buy 3 Riff Raffs for the price of 1 Tymar. I have heard the performance would be the same with either system.

Any input is greatly appreciated.

Thanks
Mark

performance is the same.

the tymar is a better looking "kit" than the 6637.

The Tymar is also more expensive. IMO you don't need a new battery tray or anything, my RiffRaff intake works just fine.

Napa 6637 filter, $35

Piece of 4" exhaust tube i had laying around, Free or buy a foot for $7 have them cut to 4"

4" hose clamp, $3

Done.


Riffraff kit is $90, i will not pay $50 for a "pre-filter sleve".

The Napa 6637 is NOT a hydrophobic filter... meaning it will accept water... the Donaldson filter is water proof.

So its kinda like having a misting system then? Any downside to a little water mist in your intake? If its filtering the air im sure its filtering the water as well.

A water soaked filter is like trying to breath thru a sponge...

I dont have an issue with the Tymar intake, but use the proper filter for the job.

This defeats the purpose of high pleat count filter with a lot of surface area if it is susceptible to water uptake. Outerwears for the filter also defeat the purpose. So just get the Donaldson filter and whatever else you need to adapt it and you will have one hell of a filter or you could just go with an AIS if you are looking for a clean/factory install. My two cents.

So if I want to go the cheaper route I can just buy a Donaldson filter, my pipe, and clamps and be done with it for probably less than $50.00 instead of $90 or $300.00. Any recommendations on where to buy the Donaldson filter at besides searching online?

Thanks
