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. More Safe Power. It's all bigger: 3.5" mandrel-bent boost tubes, aluminum end tanks, wide-open inlet and outlet with 31% bigger cross-sections and 12% thicker core area. Much greater flow volume. Increases air density for higher continuous power.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-CoolerMove 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 volumeThe 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!

We messed up!), it is still up to you to notify us within 10 business days so we can get the correct items re-shipped in a timely manner. (Prices, parts and in-stock items change often so we apologize in advance, but we must insist you open your shipments as they are delivered to see if they are correct.) If you fail to notify us within this timeframe, you will have to follow the normal 30 day return policy. Mis-shipped or incorrect items are not our responsibility after 30 days.

We are not responsible for damage claims when items are shipped to freight forwarding companies or other intermediaries and then forwarded on to another destination. The customer assumes all responsibility for the items they forward.
