The 2012+ Jeep Grand Cherokee SRT8 is a nearly perfect sleeper. With four doors, enough room for the kids and the dog, and a 475 hp 6.4L Hemi V8 under the hood pushing it to a sub-five second 0-60, there’s not much the Grand Cherokee can’t do quickly. But all that capability and power comes at a cost. 475 hp moving 5,200 lbs. around generates a massive amount of heat. It’s not uncommon for engine coolant temps to hit 220°F or more, especially in modified Cherokees.
is the backbone of your 2013–2018 Dodge Ram 6.7L Cummins. It’s responsible for
transmitting up to 930 lb-ft of torque from the engine to the wheels. That much
power generates a lot of heat and if that heat isn’t dissipated, it can destroy
your transmission. The transmission cooler does a decent job of keeping
transmission fluid temperatures in check, but only if the fluid can reach it.
cooling systems of both the 68-RFE and Aisin AS69RC utilize an in-line thermal
bypass valve that controls the flow of fluid to the transmission cooler. The
purpose of this valve is to … Continue Reading ››
If you’re like most 6.4L Powerstroke owners, your truck is your livelihood. It gets you around, carries your tools, tows your equipment, and anything else you need to get the job done. You rely on your 6.4L every day and want to keep it healthy, but your 6.4L isn’t as diligent about its own well-being.
Like all modern internal combustion engines, the 6.4L Powerstroke generates blow-by. This blow-by is made of carbon, oil, fuel, and water vapors that leak past the piston rings during combustion. Blow-by can be extremely detrimental to the bottom end of … Continue Reading ››
As Ye tightened the last bolt on our intake production sample, we breathed a sigh of relief. Over a year of painstaking R&D came to a close with that bolt.
In all our years designing intakes, few have been as complex or demanding as our 2018+ Jeep Wrangler JL 2.0L intake. We’ve fought check engine lights, tested more variations than we could have imagined, and learned a lot along the way. But the time is finally here to see the product of our efforts in its final form.
As the Jeep pulled onto the Dynojet, our anticipation grew. Would the increased flow equate to more power, or would our pipe fall flat? We removed the stock intercooler pipe from the JL and installed our free-flowing cast-aluminum replacement. We strapped down the Jeep and fired it up.
