K&N filter install
For those considering installing a K&N filter air filter upgrade, I completed the install tonight. The GS airbox is extremely easy to access. All you have to do is remove the 4 left-most clips on the front engine cover and then lift up to access the left engine cover, then remove the two clips and one screwcap on the left engine cover, unlatch the four clasps on the airbox, lift the airbox cover, swap the filter, and replace everything. Takes about five minutes.
We'll see if the $38 filter actually improves gas mileage and increases horsepower. Could be a waste of $$$.

I don't belive it does niether one of the things you mentioned 
To feel a difference you'll have to get SRTw/ecu upgrade or K&N FIPK... Both are complete intakes.... Good Luck

What was the procedure to do this on the previous model?
Thanks.

the best way to reset ecu is remove the ecu-b fuse under hood on passenger side. you have to leave it out for at least 30 minutes(sometimes longer). you'll know if it reset or not if your radio settings and seat memory are erased.

The only advantage over an oem filter is the fact that a K&N can be cleaned and re-used. Everything else is just marketing hype. When its time to change out my filters on both my GS430 and ES300,
I'm going back to OEM.

My MT 3000GT NA has an EPA estimated 19/25MPG. I have a Blitz Intake + UD pulley and a Lightweight flywheel. I average 24MPG.
I drive less aggressively in my IS350. It has an epa estimated 22/28. I get 22.3MPG =(

thanks
thanks
You really need the ECU for the benifits of the intake. Yes I believe you would experience a noticable improvement in performance with the remap in place. More agressive shifting and RPM range as well.

Performance gains: +30HP and +40ft/lb torque.
Hope this helps.

The High Flow Intake SRT system adjusts the air-fuel ratio to optimal settings in conjunction with a high flow Intake system. This system helps the engine breath much better and gives the car quicker acceleration and much crisper throttle response throughout the entire RPM range. The ECU recalibrates the air-fuel ratios for optimal performance and enhanced fuel economy. Basically the ECU tells the computer that the restrictions are not there any more and that it can breath differently giving the equations it needs to perform optimally. Just putting on a Intake pipe is not enough, the computer needs to know what to do with it when it is in place, otherwise it may get confused.
