Is it in the same general area on a 2001 LS 430? Do I need to go with a K&N replacement or can I go with a OEM like from lexus-parts.com out of Sewell Texas
Remove air filter lead in that runs along the top of the radiator. There will be two plastic fasterners one on each end. This will expose the round air filter can on your left right behind the bulkhead as you face the windshield. There will be a circular clamp to release on that filter box to split it. Be sure and line the two halves up correctly (there is a little peg that fits in a slot on the other half. Many times some ham handed idjit has broken it off so you just have to index the two halves yourslef. If you don't get it right the entranceway into the air filter can won't line up coreectly with the induction lead in. You will also have to for ease of change unplug the Mass Air Flow sensor plug and since I'm doing this from memory there may be another hose with the assembly. Loosen the two clamps that secure the ends of the plastic flex pipe that runs between the intake plenum and the air filter box, compress it and get it out of the way. There may be a 10mm bolt securing things end there. Wiggle the air filetr box out, split it in two. I spray it with Engine Gunk to clean it out inside, wash it out thoroughly and air dry with compressor air. The K&N slips right in--- be sure and put the pointy end towards you. Reassemble in reverse and go rumble. While you have the connector off you might want to take some carb cleaner and thoroughly spray out the area around and within the brass butterfly air valve. You'll see it in the front of the intake.
PS I run the K+N in everything I own and have had good results with them....
Wow sounds involved I will give it a try since you outlined all of the steps. You are a wealth of information thanks a million and I will let you know how i make out.
