Ok, Im ready to buy an intake for my 6.7 and I need help deciding. AFE Pro Gaurd 7 Dry or an S&B with an oiled. What are the pros and cons of the oiled vs. the dry. I talked to the salesman who didn't seem that knowledgeable on them, so it left me with more questions. I had an oiled on my 5.9 but hated having to wash and re-oil it. But the salesman said that the oiled filter kept more dirt out of the turbo. What are yall's thoughts on the 2 types. Which should I get? Thanks in advance

Are you sure the Pro Guard 7 is dry? I thought only the Pro Guard S was dry, the rest of the AFE line is oiled...right?

Anyhow, I heard too many folks saying they regretted getting a dry. Most said the filters allowed too much dirt through.

The 7 is a good filter, but a bit more pricey. You also have to be careful not to over-oil it after cleaning it. That's a concern with any oiled filter, though.

That's exactly the problem I had with the Prodry. There was fine dust in the intake tube. AFE sent me a PG7 when I called them about it. No more dust. AFE is a great company with great customer service, but the Prodry is not their best effort IMO.

I'm kinda fond of the dry filters cause you just go to the air compressor and blow them out. Everybody worries so much about little dust fibers well those little buggers are just going to burn up as soon as they get in the combustion chamber anyway.

Well guys, I decided to go with the AFE Stage 2 Cold Air Intake System Type Cx with Pro-GUARD 7 75-31342. I really didn't want an oiled filter but I guess I'll give it another shot.

Great choice!!!

X2! Have the same kit with the Pro-Dry S. You will be happy with the PG7. I am thinking about getting the replacement PG7 filter for mine.

Pretty sure dust doesnt just burn up in the chamber farmboy. Otherwise we would all be running mosquito netting over the compressor inlet held on by a rubber band. Silicon(dirt) and machined surfaces dont mix.

Other than the ~ $150 sticker difference, what other differences are there between the following AFE products?

75-31342

and

75-11342

Any info appreciated!

I have had the same oiled filter now for almost 3 yrs PG7 when they were first becoming known. I clean it every 25k miles, and every time the intake inlet is clean as can be. The filter gets dirty quick, but the airflow still seems nominal. I can't complain, the filter has held up great...

dry, oil plugs the maf sensor

That is if one is not cognizant of how much oil is being applied.

If conditions are mostly street and not that dirty, then dry is no problem.

However, under more extreme conditions, the oiled protects better.

AFE won't supply their dry filter for my intake on my Teryx (off-road).

Ive been racing forced induction cars for a 'few' years and NO one that I have ever met, that was serious, used a oil based filter. Every single person uses paper because the oil causes more trouble then its worth. When your dealing with turbos, the difference between a paper and an oil filter is minimal if any.

To the original poster's question, if he is really concerned about filtering the air the best and having performance in dirty conditions then an oiled filter is the better way to go. Street driving and drag racing? Then go with the dry filter.

I tow to the desert and lots of dirty conditions so S&B for me.

Another vote for the 75-31342 !



I've had mine for two years now and it's great; also had one on my 2003 RAM 2500 w/305*555.
