IRP Dual Oil Cooler Kit
 

The kit consists of Mocal 19 or 25 row cores, stainless steel -10 lines, thermostat housing, and all fittings. I normally sell these to customers to be installed in the shop because brackets need to be custom made. The reason is there are so many different bumpers available for these cars. I like the coolers to sit almost right against the bumper so the openings act as ducts. Most other kits have no ducts so you lose much of the efficiency. However, I will sell them as not assembled kits if desired. Install time is about 8 hours. Prices are under $900 for the 19 row, a bit more for the 25 row. The main benefit with the 25 row kit is the cores fill the openings of larger bumpers better. The 19 row is plenty sufficient for most applications. Here are some pics of the first kit being installed on a customer's car.

Looks like a nice kit. Any idea how the 19 row would fit with the 99spec bumper with ducts(as in the R Magic actual oil cooler ducts... not the brake ducts that mazda sells as the brake/oil cooler ducts). Thanks.

I don't have access to a set to try. You don't need the oil cooler ducts if you mount the cores against the bumper. The bumper opening itself acts as the duct.

Understood, and maybe it's just the pictures but it looks like these sit pretty much in the stock location, which would leave a gap between the 99spec bumper and the oil cooler. Am I just seeing the picture wrong?

That particular car had a stock bumper. I make the brackets to fit the car so I can mount them as needed.
