Reviews of Denso parts For Business

Just for the record, the original OEM is Denso and the W12 uses part number 471-1392 which also has the correct amount of oil in it already!
Buy a Denso or OEM Honda alternator if you want to do the job once. The cheap Chinese-made brands and auto-parts store brands will die within a year or two. Ask me how I know!
You have to lookup the valve online based upon your make/model of the A/C compressor. VW will only sell the whole compressor as a replacement. A full vacuum and refill process will be needed.
I went through 3 OEM Denso's before going with an OE (Land Rover stamped) Denso. Presto! No more charging light.
And, before you get too far, are you replacing with the right plugs? I presume it’s the 2AZ 4-cyl since you’re not asking us how to get to the back plugs. The right ones are the Denso Iridium Long Life or the NGK Laser Iridium.
I too just got a new one from Rockauto. Denso is the OEM manufacturer and I felt it more worth it than trying to rebuild. The 924S is blowing cold now after the r134a conversion.
Good job OP. I had the battery light turning on/off for months and figured it was the alternator(newish battery). Was about to purchase a reman Denso for $160, but glad I found a video of Timmy the Toolman on youtube before purchasing and went this route. Pretty easy and straightforward.
Just an update for you and a PSA: CHECK YOUR SPARK PLUG GAP ON NEW PLUGS. I too trusted that the iridium plugs that I just bought should've been pre-gapped, but I noticed immediately after a tune-up my gas mileage went to piss. Popped the plugs back out and sure enough each one was well over 1mm .
I ordered the Denso part listed as being compatible after having cross referenced it with Denso's own site along with a new condenser, expansion valve and seals. Receive the order and take it to the shop for installation. They call and say it doesn't fit. The mounting holes on the old one are 133mm apart while the new is 132mm apart. They say the bolt simply won't go in due to it having such small tolerances.
