The 21-821DS Performance Cold Air Intake System produces horsepower and torque gains by replacing the restrictive air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Nissan 370Z models. This system replaces both the left and right side intakes. The AEM Dryflow synthetic washable air filter does not require oiling and can be used up to 100,000 miles before servicing is needed (depending on driving conditions). The heatshield is a two piece design and also utilizes the factory air ducting. The intake tube is constructed from mandrel bent aluminum and has a durable gray powder coat finish. This air intake system was developed to accommodate the mass air flow sensor and PCV hose. The air intake system is backed by AEMs Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

    Great Multi-Function Watch
    Color: Gray/Digital/Gray
    I absolutely love my Timex Ironman watches. I have had many over a very long period of time. Wonderful set of functions for the price. Very affordable. Easy to use. Lasts a long time. Very easy to read in standard lighting. I like the Indiglo when needed, but do not use it too often. Absolutely love the ability to set a repeat timer to remind me to do something at a fixed interval, or to keep me on task for a fixed period of time. Great to be able to set three independent alarms. Potential to capture a huge number of splits with the stopwatch. I purchased this watch to replace a similar model with a dead battery. I have replaced batteries in the past, but it is quicker and easier to buy a replacement watch. I am saving my old watches for that day in the future when the Ironman model may no longer be available. I expect this will be my watch of choice for the rest of my life.

    Just fine if you have simple needs...
    Color: Black/Digital/Black/Green
    Exactly what I needed: a cheap, durable wrist watch. The only thing it was lacking were instructions, but about 5 minutes of messing with the buttons got it set up
