CRD K&N panel filter replacment?

CABBYGUY · **Posted:** Thu Dec 17, 2009 3:47 pm

HI All:

I have an 05 CRD and I had an 06 Gasser before it. I am wondering if installing a k&n drop pin panel filter will cause any long term problems for the turbo or engine?

It really helped the Gasser breath I am assuming it will do the same for the turbo.

Any and all feedback will be appreciated.

Cheers!

The K&N haters are going to jump in right away and say don't do it. However, I have never had any issues with them on my gas powered vehicles. I had oil samples run on my 00 Lightning that had a ram air kit (scooped air from the bottom) and there weren't any filtration issues.

I wouldn't say I hate them - but it does depend on how long you want to keep your diesel

and then if you have questions
do an oil analysis test after running K&N filter vs an oil change where you used a good paper filter

It's the TS123 - it was for the Duramax in 04
I don't know if that's new or old tech

the link has the full report

Hey AT, is that Amsoil representation the NEW filter technology of theirs? The EAA stuff?

Okay - the forum is being weird - I did not answer the question before you asked it.

If I was that good - I'd be playing the stock market - after winning a couple of Lotto's

I will sell you one cheap, used for 5 miles.

that is the old oiled foam Amsoil fitler in that graph.

Thanks JJ. Im a Big fan of Amsoil's new EAA filter technology.

I used K&N in cars I had in the past with no issue.. a Nissan Maxima, Subaru Lecacy and Subaru Outback. All gassers. I was temped to do the same with the Jeep but was flamed by members here.

I put in the Amsoil Eaa. so far very happy with it. I am not a big flag flyer for amsoil either.

Got to remember that a diesel pumps air regardless of fuel required...so it sucks in MUCH MORE AIR and needs very good filtration. The K&N does not cut it...does not cleanly filter the air a diesel pumps...

The Amsoil Ea filter has many more pleats and each pleat is longer/deeper than the stock filter...so it has more surface area than stock.

No intention to flame here--
Please however consider the amount of time a gasser is at full throttle/max air sucking-- not much or you will blow up the engine!
Most gassers cruise at " above idle 2k to 3k" for cruising etc

For "cruising" (~~~1900 RPM's) diesels are sucking all kinds of air. K+N is great for race day but bad for diesels day in and day out for ALL that air it needs.

FWIW

I used K&N for a while too. After reading a lot of stuff on other forums about them, I decided to change it out to a NAPA filter. Mine had a pine needle impelled through it...about 2" sticking out on each side. This did make me feel more comfortable with the decision. Keep in mind that anything that makes through the filter is going to go through our precision-built turbocharger. There have many discussions pertaining to this, but a gas engine intakes air in a percentage relative to its displacement as governed by the throttle butterfly. A diesel pulls in its full-displacement of air with every revolution and those with a turbo essentially pull in some multiple of that if one corrects to standard pressure.

Thanks guys, I will try the Amsoil filter, just looking for something to out perform the stock drop in.

Thank you.

I only have one thing to add when it comes to filters for a diesel. ANY filter for a diesel is critical. Keeping the incoming air clean, incoming fuel, and circulating oil is crucial to longevity.

Why are each important?

Air- Our engines are turbocharged. Any dirt that passes through the intake will be "sandblasted" through our engines. The leading edges of the turbo are the first to take the brunt. Then it's passed down into the cyls where the rings take the brunt. Gasoline engines are less keen on this since they use spark ignition. We need every bit of ring sealing we can get. Fuel is ignited by the compression of air in our cyl.

Fuel- Our engines do burn a oil. (Diesel is an oil, not a solvent like gasoline) But remember, even water can cut through metal under extreme pressures. (Waterjets) Any trash in the fuel acts like sandpaper here. Wearing our pumps down and harming injectors.

Oil- Our engines, by nature, endure more stress than a gasoline engine. The oil provides a much needed cushion between moving parts. And aids in cooling. Oil in our engine also serves another purpose. It suspends soot from the combustion process. This is why diesel engine oil is so black.

Keep all your filters clean and replace them with high quality filters. You'll have an engine that will last.

I have used K and N filters on my turbo vehicles for years and notice no issues. No turbo damage, compression losses dues to internal damage or failed engines.

Gas or diesel? I've seen a few "dusted" diesels from oiled filter setups. I'll trade 5hp for 100K+ more service.

A turbo for either will be the exact same design. My personal vehicles were gas, but when i worked for ford we had many many 7.3 and 6.0 DIT diesels running them and lasting a very long time.

Actually a number of diesel spec'ed turbos do not have the same oil sealing as a gasoline engine. (They don't need it due to low vacuum levels unlike a gasoline engine) As for the 6.0's I doubt you'd see many of them dusted. They typically blew head gaskets before getting a lot of miles. :lol:

I think another factor of failures in oilled filters is the users. People simply don't know how to clean them correctly or not over oil them.
