I paid $190 for mine and it was silver. I can vouch for AEM & Injen. The one's that sell for really cheap may be cutting corners in the filter material. I usually steer away from those. Remember, you usually get what you pay for. AEM uses K&N filters if I'm not mistaken. There's a good deal on a K&N air intake for our car on ebay. I'd jump on that one if I were looking for one. K&Ns are very functional. An air intake is definitely a great upgrade for the p5. Heck, even a K&N air filter with the recharger kit alone is a great upgrade. One thing I know for sure is you'll increase your gas mileage.
