You can't see increased silicon (sand) in your oil. If you want to run something like valve grinding/lapping compound in your engine it's your choice. I want my CRD to last as long as possible, you don't see any K&N filters on the 18 wheelers or off road diesels, there has got to be a reason if they are so good, and the increased dirt is not a problem. The fact are that if you make your money with your diesel, you don't run junk like the K&N filter. That's enough info for my decision.

Are we talking about K&N? NO!

AEM Dryflow synthetic air filters use a reinforced internal cage that is lighter and stronger than mesh types, a urethane body that will not shrink or crack like plastisol-based products, and an integrated velocity stack to increase the structural rigidity of the filler neck while improving airflow. AEM Dryflow Synthetic Air Filters out-flow ALL other brands and features with an impressive 99.4 percent filtration efficiency.

I know this setup doesn't have a K&N filter, but since it was brought up, I wanted to point out the fact about it.

Any type of high-flow filter is going to allow a little more past it, that is just the way it is. more air flow=lower filtering efficiency and high filtering efficiency=less air flow. If you want extended OCI then you don't want to do performance mods or put on a high flow filter. The same goes for chipping, more fuel=more soot in the oil....which = shorter OCI. I was simply pointing out the fact that if you are doing performance mods the slightly lower filtering efficiency isn't going to be an issue because if you know what you are doing you are going to go with shorter OCI to maintain your vehicle.

It is really just a matter of preference here....you guys are going to do what you feel is right and that's the way it should be....I was just putting some facts out there for everyone to see.

Whenever you start modifying a vehicle outside MFR specs...the maintenance schedule goes out the window. You do recover some cost with a little extra fuel economy...but again it is just a matter of preference.

Watch the speed channel and take a look at Two Guys Garage. They put these systems on Duramax, PS, and Cummins trucks all the time...and these are mechanics with 30+ years of experience.

In my opinoin, there is nothing wrong with these types of high-flow filters...as long as you are aware that you should adjust your OCI accordingly. I have never gone by mfr recommendations anyway.

I bought a filter (AEM washable synthetic dry paper) from advanced auto parts for $35 for my DIY turbocharged V-6 gasser. it seems to be a very nice product. I had a huge K&N on before that I can say the AEM dry filter is much nicer. I am also interested in high flow intake for the jeep, so those that have purchased please post pictures and reviews. also go to the fram boost website and email them about our application. two vendors = lower prices.

...Then, as I understand it, intake restriction of that degree is negligible for a turbocharged diesel.

you may think that since it has a turbo it doesn't matter how bad intake restriction is, but keep in mind the lower the pressure the turbo has at the inlet, the harder it has to work to make the desired boost, in other words a high flow intake reduced the pressure ratio (desired boost/ambient air). and if that was not enough, as a rule of thumb, every PSI less of boost you drop two PSI on the turbine. this reduces EGTs and is overall easier on the equipment.

For the record I ran an AFE Pro-guard7 air filter for 6000 miles and an oem filter for 6000 miles. Oil analysis on both oil changes. Silicon was 1ppm higher with the oem filter. Really means nothing to me though as I was looking for more mpg. I couldn't tell a difference between the two.

I didn't mean to imply that it doesn't matter how bad intake restriction is, but your post does make sense. I'm only questioning the significance of the restriction difference between an OEM filter & a performance high-flow filter. As I understand it, based largely on hearsay & testimony, that difference is negligible. The following is the best info I've seen on the subject & is what swayed me to consider OEM preferrable over aftermarket performance filters for my main concern of longevity, until I see otherwise. Before I read that, I stayed with OEM simply to err to the side of safety in my greater uncertainty. I do wonder how these results would differ for our application tho. I would think it'd be comparable unless a turbodiesel such as ours is terribly sensitive to restricition. How much would 0.02 psi translate to in a CRD & how significant would that be?

Thanks for the report!

Anyone pull the trigger on this AEM intake yet? I think I may pull the trigger here soon...I really want to try it out.

Put your $$$ toward the Snorkel that should hit here fairly soon...good clean cooler air

I pulled the trigger on this. I will report back when I get it and it is installed.

Please do as I am looking forward to reading the review.

DW, I know gassers like cooler temps for better combustion. I used to run a coiled gas line in a coffee can full of ice right before I would make a run. But how is it with oilers? I always thought they liked warmer temps, one reason why mpg always went up in the summer. I know it takes away longer warm up time, but I get better mpg when it is warm. I also know about summer fuels.

If you don't mind, what were you silicon readings (in ppm) for both filters at 6,000 miles?

I've been perofrming oil analysis myself and have found that, for me, 6,000 miles is about the magic number for changing the oil. This is due to relatively high levels of silicon after the 5,000 mile mark. So...air filter change every 5,000 miles and oil change every 5-6k on this thing.

A bit disappointing in that my Jetta TDI easily went 10k between oil changes and 20k between air filter changes. :roll:

I guess I'm looking for more air filtration, not less.

Cooler Intake Temps ... GOOD ... Cold engine running temps ... BAD ...

I'd be interested in seeing how the AEM intake works as well. Be sure to let us know if they make a provision for the MAF sensor and the intake temp sensor on the air filter housing, or if they leave it up to the customer to fudge something together for these two sensors.

To get more air flow without losing filtering efficiency, you need to increase the surface area of the filter. An intake such as this seems to be the easiest route to being able to install a filter with more surface area (but the same ability to stop dirt), without resorting to extreme reverse engineering.

Will do. Ordered it last night from prostreetonline.com. Not sure how long it will take to get it. They are in Cali and I am in Maryland. Probably at least a week or so since I chose the free ground shipping. Will check back when I get it installed.

I bought an AEM for my 02 V6 Liberty. It provided slightly better throttle response, a lot more intake noise than the stock box. Last on road trip I took, I brought along my obdii software to monitor a couple of things, i.e., tranny temps, O2 sensor performance and while doing so I checked intake air temperature. With outside air temps at 65 to 70 F, the intake air temp was 115F. While it increases airflow, it also increases IAT. I'm going to buy the original airbox bottom and put the factory oem fresh air snorkel back. I prefer the cooler outside air. Even though it came with a very well built stainless steel heat shield, it just cannot keep the hotter engine bay temperatures out like a fresh air snorkel can. The increase in IAT is approximately 15F over the stock 02 snorkel system.

I'm not sure if their system would make much of a difference in IAT on the turbo CRD. I'll have to wait for you guys to report. Be sure to take a set of IAT's before and after. It would be great to know the difference on the CRD.

Silicon was 14 ppm with the afe and 15 ppm with oem. Last change was 6 or 7 ppm with a carquest filter. Finally got the ok to extend to 7000 miles. I think most of the silicon is from the engine breaking in.

Well, I ordered it from prostreet and after a week they called and said they made an error and don't have any in stock. Tirerack.com lists it as 'special order' and the link provided earlier in this thread (listed below) shows it as being discontinued. Also, you can no longer pull up this part on the AEM website. WTF? Guess I waited a little too long to pull the trigger

I am also hearing that it hasn't even been released yet. Very strange.

Those are great readings; mine are about double that.
