The Password:JDM PowerChamber design makes more useable horsepower for normal and performance driving conditions. The problem with most CAI, is that they all look the same. It’s pretty much a filter on a stick if you think about it. It’s like trying to suck air or fluid through a very long skinny straw. CAI gives you peak gains and often flat results elsewhere on the power curve. The Password:JDM Dry Carbon PowerChamber delivers real life useable HP all throughout the power band. We spent hours upon hours engineering this PowerChamber so that we deliver to you a true performance product. Installs in less than 30 mins and requires the relocation of the battery from the stock location (Battery Relocator kit sold separately. Made by PWJDM for PWJDM using our perfected Dry carbon process, this product is one of the finest real carbon pieces you will ever find. Made using 100% aerospace grade epoxy resin with real Hexcel Carbon Fiber or Carbon Kevlar, all of our Password:JDM Dry Carbon products are individually hand crafted here in the States. The beauty about hand crafted Carbon fiber products is they are as unique as a fingerprint; no two carbon items will ever be identical. We deliver our Carbon products in its natural finish. No clearcoat will ever applied by us to hide imperfections or correct blemishes commonly associated with Polyester resin like everyone else in the industry. We strongly believe that this takes away from Carbon Fiber’s distinguished properties and therefore defeats the purpose of using quality materials such as epoxy and real Carbon. Note: Because of the sensitivity of the factory MAF sensor, we strongly recommend an upgrade to the Hondata Flashpro unit when you purchase the PowerChamber unit. A battery relocation will also be required to fit the PowerChamber. Care instructions: Please note that these parts are finished in natural dry carbon fiber, which does not include a UV-protectant clear-coat finish. We do not recommend adding a clear coat to our products. We instead recommend applying a coat of Spray-on Wax or Ceramic Coat to prevent water spots / white marks from appearing after rain or car wash.
