CSF Radiator/Oil Cooler Combo (08-14 WRX, 08+ STi)

Item # CSF 7042O
$599.00 MSRP $649.00

As many know, we here at LIC Motorsports have offered a plug-and-play LIC Motorsports custom Radiator/Oil Cooler combo kits for about 5-6 years now.  They have been fantastic...only downside was the cost associated with these custom one off kits (in both regards to manufacturing and consumers end).

Always striving for high quality engineered products and affordable to the masses, we have been working with CSF Radiators​ for almost a year now to assist in bringing a fantastic option to market for these cars.  One that not only meets but exceeds technology in its class.  We are honored to be a strategic partner on this venture and we feel that it will be a product you won't want to be without!


Technical Specs:

  • These radiators utilize a 2-row 42mm core that feature CSF's exclusive B-tube technology, as well as an ultra-efficient 6.5mm multi-louvered fin for maximum surface area contact, heat dissipation, and extreme performance capabilities.  
  • Equipped with an all-aluminum racing style drain plug for quick and reliable fluid changes
  • CSF 1.4 Bar (20 psi) radiator cap
  • Engineered and designed to be a complete "drop-in fit" install. Works with all the OEM brackets, fittings, AC condenser, hoses, and fan shrouds (only minor trimming needed at fitting locations)
  • Featuring a robust 4-plate liquid-to-oil plate-type oil cooler built into the bottom endtank. A liquid-to-oil cooler is much more efficient than a conventional air-oil cooler. Lab tested in CSF"s ISO certified in-house lab testing facility to reject heat better and at a faster rate than a 10 row air-to-oil cooler. In addition, by being placed in the bottom endtank, the oil temperature is regulated by the thermostat of the cooling system. Never have to worry about operating temperatures not warming up fast enough in cold weather climates. 
  • Complete with 2 AN-10 male fittings and is compatible with many popular aftermarket engine and exhaust manifolds.
  • This kit comes complete with a machined thermostatic sandwich plate made by Greddy and forged right angle -10 fittings made by BAT.
  • Topped off with the industry's finest 1 hour hand polish "mirror finish" for a look that matches the performance.


Additional Technical Notes:

  • 08-14 WRX, which have no factory oil cooler, requires an additional sandwich adapter to space the Greedy unit down (to clear block/pan)


Kit includes:

  • x1 08-14 WRX, 08+ STi Radiator/Oil Cooler
  • x1 Greddy Sandwich Adapter
  • x2 -10 Right Angle AN Forged Fittings


Adapter for 08-14 WRX

On the additional adapter, are you suggesting to get and stack another Greddy part #12401126 together to make this work?

LIC Response

On the 08-14 WRX's we use a universal Greddy Adapter, which is part number 12002801 and the adapter provided by CSF.

STI 2012 Hatchback - AT

Will this be direct fit to STI 2012 hatch with Auto Transmission?

LIC Response

This is for the MT models

Oil Cooler Thermostat Setting?

Hi, I've installed the CSF combo radiatior in my '11 STi sedan, and street temps dropped from 210F to 180F according to my AutoMeter oil temp gauge, picking up the oil temp at the sandwich plate adapter. At what temperature does the oil cooler thermostat open? Thanks, Laz

LIC Response

If I recall correctly, the Greddy t-stat is 175* F but not 100% sure

Do you also sell the prebuilt lines?

I'm looking at installing on a otherwise stock 2015 STi, Can I also get pre-sized lines with fittings?

LIC Response

We don't, I'm also unaware of anyone offering pre-assembled line kits for these.

Killer B pan

So I just received your CSF radiator kit. I go to install the oil filter adapter and it doesn't fit flat to the surface at any position with the killer B pan. There's only one way it would fit and that's the oil line ports facing the exhaust and it's way to close. Is there another way? Maybe a different style adapter?

LIC Response

That's correct, there is a lot of variations between aftermarket headers, oil pans, etc that will make it not plug and play out of the box. In cases like this, we've always used the factory oil cooler as a spacer to create room for the sandwhich adapter/AN lines and fittings.

Expansion tank and fan shroud

Is there an aluminum expansion tank that fits or does it reuse the stock? Can the mishimoto plug and play fan shroud fit?

LIC Response

This kit uses your stock fan/expansion tank setup. I have never used Mishimoto fan shroud, so not sure if it does or doesn't fit

Available ?

Hi, Are they available now ? Thanks !

LIC Response

Yes they are!

Will these be available again?


LIC Response

Yes, just currently on back-order...ETA is 3-4 weeks

Track use

Would the two row rad be sufficient for track work? Any real life testing results? Thanks, Walter

LIC Response

Considering the factory OEM radiator is 1 row...going to a dual aftermarket and larger capacity is a must! We have a few folks running them on street and track, no issues.


Will this fit KillerB header and KillerB oil pan? (2012 Sti year specific)

LIC Response

The radiator itself would have no issues, as its a direct replacement fitment. How you route the lines and adapter might on the other hand need to be done differently for fitment but the radiator/oil cooler itself will not be an issue.

Is this currently in

Is this currently in production or is it in-stock?

LIC Response

These are now in stock!

Ryan B

I need to set up an appointment to get this precious piece of engineering installed while I need an oil change as well.

LIC Response

Give a call to setup an appointment

LIC Response

Production is done, they are going through QC, then boxed, then shipped to us. Projected to have these in 2 weeks.
