I am looking to replace my exhaust manifold in my 2002 IS300 with 206K miles. I am reading code P0430 and have replaced the B2S2 sensor last week. In looking a OEM part numbers, I have found 1714046080 is the "correct" 01-05 GS/IS part.


I have found the 98-99 GS300 OEM exhaust manifold PN: 1714046030 for considerably cheaper. Would this part be a direct fit? Visually it appears to be the same part.


Any help or advice on this would be appreciated! I need to get this to pass CA smog in the next month.
