Anyone have experience with a K&N on an 84 300TD. Is there anything to
be gained by going to one?

Your turbodiesel is not being choked or strangled. There will be no gain with a K&N.

You gain a bit more airflow (that you cannot use) and significantly more particulate matter and dirt from the air (that the engine doesn't want).

If u are talking about putting it in the stock air can, u wont gain anything, just use the oem paper filters, they provide suffficient airflow.

No gain whatsoever. Maybe 0.0001 seconds faster 0-60 from your lighter wallet.

on most older european cars, the oem filter design has so much airflow, that a k&n provides no benefit.

OH NO! Not again! Look, there are many who claim it will riun your motor and if you do not oil it properly it will. If you live in a really dusty area like I do, properly serviced you will get slightly better performance and longer filter life, but your unlikely to feel it at the accelerator. I have one in my 1983 300D and no regrets.

^^^^ what knightrider said. i had a 1974 dodge ramcharger 4X4 that came with a oiled air filter as oem equipment that had instructions for dusty service blah blah blah.

Oiled gauze/cotton and oil bath filters are very different technologies.

The trick is to make your oil gauze cotton filter an oil bath filter housing!

Do not use it Period.

pearl black 1983 240d 4speed (Converted!@$$%) atleast the tranny was rebuilt.

There has been detailed study on a commercial diesel engine with K&N versus paper and felt filter, conclusion was K&N let in more dust and the CFM air intake factor was nothing significant over paper or felt.

Filter Efficiency is a measure of the filters overall ability to capture dirt.


In the chart below it’s important to note the different test durations for each filter. The AC Delco filter test ran for 60 minutes before exceeding the restriction limit while the AMSOIL and K&N tests each ran for 20 and 24 minutes respectively before reaching max restriction. In 60 minutes the AC Filter accumulated 574gms of dirt and passed only 0.4gms. After only 24 minutes the K&N had accumulated 221gms of dirt but passed 7.0gms. Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt.

Does AC Delco make cone type filters?

Edit: Nevermind
