I am curious if anyone knows an equivalent replacement oil cooler for the Airflow system 2006x-x that is installed in RV14 models. Throughout the years I have heard that stewart warner is a superior product and if there is one that directly replaces this model Airflow systems, I will be very interested and appreciated for the info.

I used the Aero-Classic HE series as recommend by Pacific Oil coolers.

Hi Walt,
Do you remember which model and/or replacement of the 2006x. In a 14, I am limited to the width if using the default mount location.
 
I installed the P/N 8001649, but I would suggest a quick call to Pacific oil coolers just to verify.
This is the cooler I installed on my 7 with my IO370 HC which has piston squirters, oil temps are not an issue.

SW/Troy/Meggitt 10611R should fit the bill...

The 80001694 is a dual pass arrangement, equivalent to the SW 8432R/S and NOT the same as the Airflow Systems 20006A

See https://www.airflow-systems.com/wp-content/uploads/Airflow-NDM-Drawings.pdf

Brian,
Thank you for the info. I found the SW10611R and it does look to fit as it has the same mounting hole/size as the 2006x but I did not find te 106611S dimensions or performance data.
Do you have any info or experience of the cooling efficiency in a real world experience. Based on the graphs provided for 2006x and SW10611R, it looks like the Airflow seems to be a bit more efficient, if I am reading/comparing the graph correctly.
 
It is in the last link -- the SW10611R charts start at page 21 (or 23 / 66) and 10611S charts start on page 25 ( or 27 / 66). Aside from a relief cut on the front/top face of the 611S, they are the same performance-wise.
