One of my coils went yesterday (PO304) and according to everyone it is best to replace with OEM Denso 673-1301, which is what most sites recommended for my 2000 RX300. I recently bought this so I am not familiar with history other than what was given me. So I ordered and today when I went to replace it I noticed the one I pulled was Denso 90919-02234, as were the other 2 I could easily see. Can any of you shed some light on this 1) interchangeability / compatibility, 2) Reason for different coil (reduce sludge problem etc., better performance, more economical) 3) Should I replace the Denso 90919-02234 with another or replace all with Denso 673-1301. I know this is one of the areas to stick with OEM. Thanks Apologies if this has been covered, but I have not seen this come up.

the 673-1301 is the correct part -- i just changed mine this week. the one you replaced is probably some old model, don't know where you got it from it seems to be discontinued.

Welcome to ClubLexus.

One of the reasons to purchase from the dealer is that they keep track of obsolete and discontinued parts. One should always take the vin number to the dealer. Dealer may not be the cheapest way. They should know the answers to the question you asked. Here on the net, you will get opinions, most of the times they will be right .... well you just got mine. I almost bought a discontinued bearing from the net once.

[Note: some times the change is not necessarily for the better]

Thanks - I will make the call / trip tomorrow and see if they can make sense of this. It seems that the DENSO 90919-02234 (superceded by 90080-19016) is used in the below as well: (Toyota 6 -cyl 1MZ FE). They have been installed in mine and working fine until now. I wonder about the difference, since all the other (5) coils are DENSO 90919-02234, should I continue to use that as my replacement? I am going through the previous paperwork to see when if ever the coils were changed. I guess Lexus should have a record for work done there which was the case I am told. As you can imagine I prefer to change 1 on the easy side than all 6 !! Now I have the Denso 673-1301, but wonder if I should install that or return it.

I JUST TOLD YOU I installed denso 673-1301 this week. Check any retailer and they will show this part as the correct one. This is DENSO'S part number you are looking at TOYOTA part numbers.

RXy

Thank you - no one differentiated between Denso pt # and toyota /lexus pt.# previously that I've seen. So they would be the same then, compatible and interchangeable. That was my original question. I mistakenly figured that since Toyota is Denso the pt #'s would be the same. Usually shops cross reference to the OEM part replaces or exact fitment ...but I have not seen this and so I asked.

hsmac

usually toyota parts will have those long 10 digit part numbers. there may be some difference in quality control standards between oe and oem but i assume the difference is negligible.

New Lex / Toy Pt. # 9008019016 ; (old) 9091902234; Denso Aftermarket Pt # 673-1301. Ignition coil. Installed 673-1301 and now back on the road. Thanks FYI Lexus wanted 145 for the part, and aftermarket Denso 58 from online.

hsmac

the lex/toyota pt #'s are the same? i know sometimes lexus sells toyota parts, but i'm guessing lexus does have lexus branded parts for each part.

here's a tip... toyota parts are usually the same as lexus and a lot cheaper so just buy from toyota. once i drove 30 min to a lexus dealer to pay more for parts that i could have gotten at a nearby toyota (which seem to be everywhere) for half price. wish i had known.

Lexus parts usually come in a Toyota box. Never seen a "Lexus" box(?)

hsmac

there are lexus branded parts, but sometimes lexus gives toyota parts still at the premium price.

Just adding a bit of humor ..

If any one buys parts from Toyota and not Lexus, they should have no problem in acknowledging they drive a Toyota.

I'm wondering if the ignition coils ever gradually fail or if they work perfectly until one (or more) quits altogether and a code shows up. I plan to replace the three rear coils if I ever change the valve cover, but is there any point in replacing the front (and easy-to-reach) three as long as they still seem to work?

salimshah

I had to replace only one at around 120k. ,, That again tight after installing new spark plugs. The other five are still working fine for many years.

I would suggest just change what you must ,,, unless you are worried about being stranded. You can preemptively change many things as the vehicle ages.
