12.9 hp and 4.2 lbs. feet of torque over baseline
3,000 rpm where most of us feel the is-f needs a little pick me up, the importtuner is-f recorded a gain of 15 hp and 25 ft. lbs. of torque!
I'm convinced, and driving year round in San Diego where it's 82 and calm shouldn't cause any "heat soak" issues

Well Ive had the K&N intake for a couple of months
I got it mainly because I got a great deal on it (my fiancé got it for me as a gift!!). But I thought Id give some feedback. One thing I noticed about it was that there was some serious heat soak after driving pretty hard in 90+ California weather. How did I notice this
well after awhile it feels like the car is lagging and trying to pull, in other words, there was a serious loss of torque and power.
When you look at the K&N heat shield, you can easily see how poorly designed it is. Its made out of metal, there are gaps all the way around the shield that allows for hot engine compartment air to be sucked in, especially in the bottom portion of the shield there is about a 1 inch gap. After a spirited drive, if you touch the K&N cone its pretty darn hot!! So what I did was go and get some thermal shielding and a Nomex intake tube shield and thermal shield the intake as much as possible. I close off all the gaps where hot air maybe sucked in and the only area that is open is where the stock front intake scoop opens into the K&N intake where it will only draw in cooler air from the front. Now even after a very long drive, the K&N intake is much cooler to the touch. Also its much smoother than before, and it feels like there is more power...but I cant fully claim that without a dyno to back it up. Im sorry, I havent gotten it dynoed yet I need to save for the wedding but Ill do much best to get it done soon and when I do, Ill post the results. Below are the pictures of the thermal shielding of the K&N intake Darshana S
PS...It sounds badass too!![Big Grin](https://www.clublexus.com/forums/images/smilies/biggrin.gif)
