MAF sensor is built into the airbox lid so doesn't get touched. Smoother pipe should give a less interrupted airflow. Not sure about added noise. I think that usually comes from a bigger hole in the airbox (like the F-Sport one).

Mine runs 4.5% too fast as measured by several GPS units. When I used to run 20" wheels on the car (285/30/20 on the rear) the speedo would read exactly correct.

Pipe between the airbox and inlet manifold. Change the flex/plastic pipe for something solid and straight.

Yep, PS4 are excellent... last two sets of tyres on mine have been PS3 and now PS4 From your list, I wouldn't buy anything less than the Hankooks. I have an odd distrust for those cheap/random brands.

This was the easiest solution I found a while back: https://www.tp-link.com/au/home-networking/entertainment-device/ha100/ Cheap, not permanent, sound quality is decent. Still have to control music from your phone though. No biggie if you have it in a holder already.

I'm about to hit 120,000 in mine and will get Danny (ilv1004s) on here to change it pretty soon.

Toyota part number 87139-07010 for the cabin filter for a 2009. Assuming it's the same for a 2011.

Still drives exactly the same as when I picked it up from the dealer. Just keep up proper maintenance and any Toyota/Lexus should last (nearly) forever.

Okay great, I'll give you a call early in the new year. My box is around 115k and I'd like to do some preventative maintenance. Car just hit 10 years old a few months ago.

Danny, do you flush the 2IS box and if so, how long does the procedure take and final cost?

I thought I read during the time of the first recall that faulty bags had been sent out as replacements and would need re-doing in the future. I guess that time has finally arrived.

Danny, where's your suggestion to source front & rear bars for a late 2009 IS250?

Performed a bit of cleanup on the idiotic spam posts. Amazing how these users only posts are links to locksmiths outside the country.

Best off using a Lexus approved repairer... they should have proven their ability to colour match to Lexus' exacting standards: https://www.lexus.com.au/owners/find-a-repairer
