While t-shooting a gremlin in my 2000 Honda Accord that sends intermittent misfire codes, we discovered that the EGR was not a Honda part. I have absolutely no idea when this part was installed.
Scrutinize the images below. Notice the exhaust port on the Honda EGR valve (left) is half the size of the aftermarket EGR I removed from the engine. I gather Honda engineered the smaller port on the OEM EGR to restrict the flow of gases.
The EGR sends its valve position to the computer. The aftermarket EGR in the image below would deliver approximately twice the volume of gas at a given position compared to the OEM part, thus throwing off the computer. I wonder if this smallish disparity between OEM and aftermarket EGR valves contributes to, or causes, the intermittent misfire codes …one dares to hope.
Honda engines are reputed to be picky about the use of particular aftermarket (non-OEM) parts. Perhaps this list includes the EGR?

I would like to use honda parts, but they are so expensive. I have had success with these aftermarket parts/fluids for my 99 civic:
1. Bosch O2 sensors
2. Dorman exhaust manifold
3. Transmission fluid
4. Fuel filter
5. Brake fluidSo far no problems. I know that Eric only recommends Honda transmission fluid, but I didn’t know that at the time. I had no problems while using it and since then I have switched back to honda transmission fluid.
The Biggest mistake I ever made was on a v-6 Timing belt that when I compared the O.E.M tooth for tooth to the aftermarket it did not line up! Of course it ran like crap.
Won’t ever make that mistake again. Certainly it was extra money, but was it really “cheaper” when I had to tear it all back down and buy the O.E.M anyway?

You might be surprised, but many times dealers also use aftermarket parts. Our local Ford dealer buys many of it’s parts from the Napa Auto parts that sits right next to it.
Not only that, but many of the “genuine XXXX parts” are aftermarket. Honda’s oil is the exact same you find in the Motorcraft box.
In a nutshell, Exxon-Mobil (XOM) was Honda’s supplier for its bottled oil products for years. Approximately eight or nine months ago, XOM lost its contract to ConocoPhillips (one word)(COP).
COP, as you may know, also happens to be the supplier of Ford Motor Company’s bottled oil products under the brand name Motorcraft. If you return to bobistheoilguy.com and search the Virgin Oil Analyses, you will see that the analyses of Honda Genuine Motor Oil, both the synthetics and the semi-synthetics (Part#s 9036 and 9037), are virtually identical to their Ford Motorcraft counterparts.
(As an aside, Mobil Clean 5000 is now Mobil Super 5000. Alas, it’s no longer as robust as the old MC5K.)
Back in ’06 Honeywell made Honda’s oil filters (well Filtech made the ones that are installed by the manufacturer, Fram makes the ones the dealers stock), yep Fram made the filters.
Autolite makes many OEM spark plugs and for a while was actually owned by Ford motor company.
The only fluids I get from Honda for Hondas is transmission fluid, the rest I just buy quality aftermarket (its pretty much the exact same thing you get from the dealer).
Yes Mckrishes is saying right. Even I have used aftermarket radiator bought from iautobodyparts in 2013 Honda Accord Crosstour. By far there is no problem occurred yet in it. Although I understand that it’s better to use O.E.M parts, if the budget is in your favor. But there is really no problem in using aftermarket parts too in terms of quality, functionality and work performance too, even they are very cost effective.
