Difference between Stillen oil cooler kits
 

I am about to get oil cooler for my Z and I see that there are four different kit for Stillen oil cooler kit.
I am thinking to get either performance kit
STILLEN Gold Series Oil Cooler Kit - Performance 400643 | STILLEN

or street kit
STILLEN SETRAB Oil Cooler Kit - Street 400637 | STILLEN

But what is the difference between these it beside size of core?
I see that performance kit comes with bigger core with 25 row than street with 19 row but for some reason, street kit is more expansive.
Both comes with Thermostatic Bypass Plate and I don't see any description of their difference.

If anyone has idea, please let me know~
Thank you in advance.

the street kit is more expensive because it has a Setrab unit included with it where as the performance kit comes with one of stillens own in house designed oil coolers which is why it is cheaper. not really sure of the effectiveness of stillens oil cooler as i don't really know anyone on the boards that owns one, but setrabs oil coolers are among the best on the market which is why they charge a premium on any kit containing one.

I see the difference in pictures.
Thank you for fast response!
BTW, what oil cooler do you have? Im not sure which oil cooler is good enough for socal weather for just street with some spirited driving..

The bigger the better for Socal weather.

Im currently running a 34r, And have been pretty happy with the cooling effectiveness.

I believe most of the people here run Z1 oil cooler. I might be wrong though, but that is probably what I'd (and will) go for

I got the 25 row stillen designed one. They claim it has the same temperature drop as a setrab unit and it has been pretty effective for me.

One word of advice, the mounting bracket provided is designed to relocate the ps cooler and mount on the passengers side. I didn't want to do that so I drilled 3 new holes and mounted it on the drivers side. Pretty easy to do but I wish I knew about that before.

Stillen unit also comes with built in fittings on the core so you cannot cross thread during installation.

Z1! Don't need to relocate anything!!!

If the core oil cooler isn't a Earls, Setrab, or Mocal it's likely Chinese made. Some of the Chinese oil coolers are pretty poor quality.

I'll second this ^. Great kit, easy install, good price.

Whats the real difference between Mocal and Setrab???

I recieved my fast intentions oil cooler in the mail today. Ill let you know how it is when I get my nst pulleys in and hfcs.

Color...location of corporate home office...end tanks on Setrab have a plate style cover. In reality they are very similar, but I doubt that you would ever tell a difference quality or performance wise.

Just my personal preference.... I will take the Setrab.

I'm running a GTM Setrab 34R oil cooler but of course I'm dealing with Texas Weather:shakes head:...But its Effective that's for sure :tup:

Thnx
