DIY Intake vs. drop in filter.

[Loneranger]

Is a DIY intake better or just a good high quality drop in filter? Some guys say with a DIY, the air you draw is hotter, so its not even worth it. Your better off with a high performance drop in filter. What do you all think?

[Dietoremain]

I definitely felt the difference. I think the stock box is just too restrictive.

Well it's hotter when your sitting at a light but goin down the road it's pretty much the same as a closed drop in

Every time I installed a open element air cleaner oin any of my trucks they caked up with dirt quickly ( I go hunting fishing etc so i do lots of dirt roads)
I basically do a foam reuseable air filter drop in style and leave it at that. I will not use K&N filters i rather use the factory paper element filters

[DJM]

I do the same thing I'm constantly on dirt roads and I have never seen any dirt in my intake tube with my K&N it does have an outerwear on it also been like that for about 156k miles it's all about maint on the filter kind of like an oil filter you can have the best oil filter but if you neglect changing it your oil bypasses the filter. I do agree though I wouldn't run one in real dusty environments without some kind of outerwear or foam pre filter .

Get the DIY intake and a Riffraff prefilter and you won't have anymore problems with dirt.

And K&N anything you want to stay away from as their drop in filters and cold air intakes do not seal properly and have dusted quite a few engines.

[Rob454]

I just had problems with K&N filters on my other trucks ( tons of dirt on the filters and the intake tubes) needless to say the filters did not stay on there too long. I just went back to the factory paper style filters on my trucks. Sold the K&N filters on craiglist

So I ended up going with the 6637. Do a lot of you guys use a pre filter or something like that with these?

[Dietoremain]

yeah, where did you get yours? hope you didnt pay over 40 bucks. riffraffdiesel.com has em dirt cheap.

Just a FYI..a DIY 6637, which is neither a Tymar nor a recommended system by us. The WIX/NAPA 6637 is not a hydrophobic (water resistant) element and using it as an open element should be avoided. There are other concerns such as providing minimal radial clearance, isolating engine vibration, positioning away from rain drip channel, etc. But, I just wanted to draw a clear difference between copies, DIY efforts, and a Tymar.

The Donaldson filter is very resonable and many times as cheap or cheaper than a 6637
