At the heart of the system is an Airaid Premium Series high-flow conical air filter that is protected from the engine by their innovative Cold Air Dam (CAD) design.The air filter itself does an excellent job of providing a good flow of clean air in the worst conditions, thanks to the combination of Airaid's proprietary Syntha Flow design and multiple cotton gauze layers. In fact, the only items we needed from our Gear Wrench tool sets were the following: a 3/8"-drive ratchet & extension; 5/16" & 10mm sockets; 7/16" open-end wrench; 3/32" & 5/32" Allen wrenches; and a Phillips Head screwdriver.Our goal at the end is to have a truly unique 4x4 for the avid off-road adventurer... Namely you get added value out of whatever it is you purchased.
(We'll see what we get when it comes time to do the dyno runs and fuel-economy tests later in the project.) Another claim, one which we are pretty confident in its accuracy, is Royal Purple engine oil extends the oil-change interval from the customary 3,000 miles to 12,000 miles.
Even at /quart for Royal Purple, this makes economic sense even if nothing else matters.
A bigger reserve is a good thing to have when you're adding heavy electricity eaters such as a winch and auxiliary lights.
But the new Tundra doesn't make dual-battery installations easy.
Truth is we couldn't find any spare real-estate under the hood to put a second battery. We swapped the factory battery for a more powerful replacement from Optima.
The model we chose is an Optima Yellow-Top - a dual-purpose starting and deep-cycle battery designed for heavy-duty commercial use.
Their new Tundra 5.7L Cold-Air Intake kit #510-213 is designed to provide a relatively straight shot for the air, coming in around the passenger's-side headlight, to get to the intake.
Included with this system is an intake tube that is specially designed to accommodate all the factory hoses and control devices found on the new Tundra V8.
But it still employs a circuitous route for the air to take on its way to the intake manifold.
This is because the engineers favor lowering sound levels over higher engine performance.
That means the engine and drivetrain are going to get a workout - and what better way to protect the vitals than to immerse them with synthetic lubricants designed for racing and other severe uses.
