Banks Power 04-05 Chevy 6.6L LLY Techni-Cooler SystemOptimizes the boosted air density for higher continuous power and lower exhaust gas temps. Restriction free for superior flow with 25% larger core area and 34% more volume. Big boost tubes & durable cast end tanks pack cool, dense air into cylinders. Cooler EGTs, more MPG & constant duty power. It doesn't get any cooler than Techni Cooler Move over, pipsqueak. The stock intercooler has an inferiority complex. No wonder it's smaller than Techni Cooler

Optimizes the boosted air density for higher continuous power and lower exhaust gas temps. Restriction-free for superior flow with 25% larger core area and 34% more volume. Big boost tubes & durable cast end tanks pack cool, dense air into cylinders. Cooler EGTs, more MPG & constant-duty power. It doesn't get any cooler than Techni-Cooler Move over, pipsqueak. The stock intercooler has an inferiority complex. No wonder it's smaller than Techni-Cooler in every aspect: boost tubes. core area, inlet/outlet, even the end tanks. Most competitors use poorly designed sheet metal end tanks and provide inadequate flow volume. Banks cranks up the volume. Banks improves airflow into and out of the intercooler with big mandrel-bent 3 inch boost tubes. Large, rugged, high-efficiency cast end tanks that won't rupture under high-boost conditions. A huge inlet and outlet. And a 25% larger core area with a whopping 34% improvement in volume The king of cool. Removing restrictions and improving airflow lowers boost air temps. This increases the density and oxygen content of air entering the engine, which amplifies power, lowers exhaust gas temps (EGTs) and improves fuel economy. When EGTs are tamed, the tuner doesn't need to limit fuel delivery. So you get higher continuous, useable power and more power at any EGT. Very cool! Everything about Banks Intercooler is bigger, it doesn't get any cooler than Banks Intercooler. Key Features: Optimizes air pressure and distribution going into the intake manifold. High-efficiency custom-machined durable cast end tanks. Raises boost without increasing turbine drive pressure. Cooler EGTs, more MPG & constant-duty power. Improves flow of oxygen-rich air into cylinders 25% thicker core with 34% more volume. Improves Power, Durability & Fuel Economy. Packs cool, dense air into the cylinders. Accommodates stock mounting points. Lower restriction for superior flow. 3 inch mandrel-bent boost tubes. 2-year Warranty

The best lower unit gear oil I have used
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
I have been boating my whole life, this is by far the best gear oil. I use this in my Johnson 115 even though this is technically made by Mercury. I seem to get less if any water intrusion into my gearcase with this oil. If there is any, the oil emulsifies the water and continues to protect the gears. I have had better luck with this than Pennzoil marine or others. Highly recommend. It is a blue color and easy to drain and fill.

Does not come with a pump.
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
The Good: Changing the fluid in the lower unit is a very easy DIY job. This can save you hundreds of dollars each year by doing it yourself. The Bad: You need a special pump to change the oil, and sometimes it comes with the gear lube. Unfortunately this product did not come with it. Luckily my neighbor had an extra one from changing the lube a different boat laying around and was able to use that. The Ugly: If you have to go get the pump, that could cost a few extra dollar but is just an extra nuisance. The pumps are interchangable but you just need to clean it between uses (DON'T MIX DIFFERENT OIL BRANDS)
