The part I am talking about is the rubber round seal shown under the metal hose clamp. On the right image, the seal is at the very top left, next to the 90 degree ell. The rubber seal has a notch cut into the top outer flange; this is to match it to a metal alignment pin at the top of the manifold round inlet. What I want to know, is why Lexus/Toyota only sold the seal as part of the entire unit shown on the right? Looking at the two images to the right, you will see how image #1 fits the manifold opening.  It appears to have not been bonded with heat or a cement; just slid over the plastic end and tightened to the manifold with the metal screw clamp. All I really need is the RUBBER SEAL. Being a boat mechanic for many decades, we used to fabricate things like this all the time, but I have sold that business and don't have access to rubber seals like I used to. However, the word "seal" makes me wonder if I might use a seal from an axle to hub arrangement? I'm off to search.....Chime in if you have a better idea. 

I am aware of this one, but the repaired nipple concerns me. Thanks anyway, we might buy it just for the doggone rubber seal!

Hello members. Our 1999 LS 400 was making a loud sucking noise on the first four gears, but quieter in fifth. I replaced the round intake air filter, cleaned the housing, same noise. I removed "air intake inlet muffler resonator" aka....Snorkel leading to the intake manifold and discovered the last mechanic had forced it on and the rubber seal under the hose clamp had been distorted and folded toward the radiator, restricting air flow and not sealed properly. There is a notch at the top of the seal which was torn, so contacted our local Lexus parts department, only to learn the seal is serviced as part of the snorkel and sadly, all of it no longer manufactured. I had to turn the seal 180 degrees and cut a new notch on that side, cleaned all surfaces, used a rubber cement to hold the altered seal in place, sprayed silicone on the receiving tube and with a lot of struggling, got it back on. I think my idea has failed, as the motor is roaring again. There is not enough room under the manifold inlet for the snorkel to be easily slid on. Can anyone help me with a better or different seal and how to slide the snorkel on more easily? I might consider a complete snorkel new or used PN 17875-50160. 

This is not like Lexus; the seal should be sold separately and if they can't make anymore, the least they could do is offer the design specs to an aftermarket company. Thanks, Wayne

Our 1999 LS400 vin JT*BH28F7X0141405 has a cabin air filter "holder" and I think the last brand of filter was a Denso. I ordered from eBay a Delco filter with this description on the ad "Cabin Air Filter-HEPA Cabin Filter Bosch 6045C fits 93-00 Lexus LS400". It will not fit the holder at all and cannot be forced into the filter slot. I have looked at the Bosch website and it indeed, state that this is the correct part number. At this point, I'm ready to order from whatever the OEM filter was made by. Can someone tell me the correct Denso part number? Photos show the differences between the old and new. The old one fits down inside the holder and the Bosch bows up because it's too thick. Thanks in advance
