I've been looking around and can't find anything comparing the two SRI's. I'm looking at purchasing one of these, and can't find a definitive answer of which is better. From what I can find, K&N: Approx 6-7 HP gain. 3-4 mpg increase I've read though that the K&N actually brings hotter air into the engine. Replaces stock intake system Install time about 30-45 min Oil cone filter Takeda: Approx 10-20 HP and torque gain Utilizes stock airbox allowing actually cooler air to enter the engine (unlike most sri) Dry cone filter Install time 30min-2hrs If someone can update me on the MPG increase with the Takeda that'd be great. Any other opinions are appreciated.
