Hey everyone.

I was asking a few questions on the D-series forum about the S2000 15400-PCX-004 oil filters and I got some really good info from the guys at Endyne (www.theoldone.com).

Mind you, this was all regarding a D16 motor, but I'm pretty sure that this S2000 filter will work on nearly all Honda motors.

Just thought I'd spread the info. Enjoy.

In a post I made on the D-series forum (http://www.d-series.org/forums/showthread.php?t=87935) I mentioned that I did a little more research and found that the HAMP filter H1540-RTA-505 is not the same as the OEM filter 15400-PCX-004. It is the same as the smaller OEM filter 15400-RTA-004. When I last changed my oil, I took a pic of the HAMP filter, the OEM PCX I had on, and a Canadian Tire Motomaster (Fram I think...) filter I had sitting in my trunk to see the size difference. Here it is:

The HAMP filter is noticeably smaller than the OEM PCX, and even smaller than the Motomaster filter (regardless of size, the HAMP is an obviously better filter than the MM...). I added the bottle to give something to compare to in size. Here are the rough measurements I took:

HAMP RTA: 85mm tall, 215mm circumference, 65mm diameter
Volume = ~282 cubic centimetres (~111 cubic inches)

OEM PCX: 85mm tall, 255mm circumference, 85mm diameter
Volume = ~483 cubic centimetres (~190 cubic inches)

CT MM: 85mm tall, 245mm circumference, 75mm diameter
Volume = ~376 cubic centimetres (~148 cubic inches)[/align]

for 99.9% hondas on the road, a simple good name brand or honda oem filter will work just as good or better than any other. although it has been known that the s2000 filters fit the d16 block, it's not recommended due to the fact that the oil flow rate in the s2000 block is slightly different than the older d16. so my suggestion is to still rock the honda or oem equivilent.

The reason Imade the original post was becasue I got some good info from the tuners at Endyne (www.theoldone.com) regarding oil filter and oil pressure. I had just rebuilt myd16y8 after I spun rod bearing 4 and wanted to learn more about increasing oil pressure and what oil and filter to use.

When I emailed the guys at Endyne, they told me that the only filter theyrecommended was the PCX for the S2000 because of it's larger size and decreased resistance which helps to keep oil pressure consistent.

You can read it all at http://www.d-series.org/forums/showthread.php?t=87515.

But either way, usingan OEM filter for any Honda is obviously a good choice, but I was looking for the best option available and thought I'd share the info.

i see what you're going for, and i've already read up on this topic for a long time. it's just that when it comes to a factory spec honda motor, you need to run the designated filter for the block. when you increase the oil pressure for built motors, it might be a good idea to do so, but until then, i recommend keeping the stocker.

p.s. it doesn't really matter what type of oil you run and what filter, as long as it's the recommended weight and viscosity from a good name brand (i.e. royal purple, penzoil, mobil 1, castrol) , then your motor will run the same as if it were on 100 dollar oil.
