The APR Air-to-Water Intercooler System for the B9 RS4 / RS5 2.9T EA839 offers a substantial leap in performance that directly translates to more horsepower and torque, and consistent performance that’s unmatched by the factory cooler. The factory cooler struggles to cool the charged air resulting in excessive intake air temperature due to its small size. This struggle results in ECU protecting the engine by pulling power during a single quarter mile pass, lap around a track, or even during a spirited drive. Simply bolting on the APR System relieves this issue, resulting in an instant boost in power and consistency. The APR system has no trouble remaining consistent thanks to its ability to resist power-robbing heat soak!

Good color, but expensive
Style: Cartridge Ink
Frankly, as with other printers, I thought that I could use reconditioned cartridges with this printer. The first set I purchased was not recognized, thus I have had to purchase genuine products. The cartridges, also offering good color, do not last long. It's a trade-off between cost and quality. If you have to go to Staples from dire need, be sure to price match, for Amazon is $1 less than Staples. Staples will match Amazon. Overall, I try to buy from Amazon.

Big Print Outs Look Great With Epson Ink
Style: Cartridge Ink
So I paint and I'd been trying to find a way to print out large pics to aid me when I'm trying to get my shading correct. This ink is fabulous...the printer just does a great job. First I print one in color and the second in greyscale...it helps a great deal when working with the shading. Epson can even add a couple other color cartridges to get different effects. I'm very happy with Epson inks. They really made a good selection of colors to make prints look amazing. 5 stars
