I went to my local Murray's parts store. They had two styles of 18mm anti-fouler plug adapters. These were Motormite part numbers 42002 and 42009. They describe 42002 as being tapered. Which one do I want?

 

Just Installed 18 mm Adapters, took 15 minutes total, haven't seen CEL (It was on for 8 months) , i am very happy , thanks guys

 

Thanks Derek!

I've been fighting a CEL for the last several weeks and the anti-fouling adapter mod is working.

Just a note to add to Dereck's, make sure you get the adapter that uses a gasket and not the tapered seat.

Also to note.... what can be done to make sure these don't turn into a glob of rust?! I can only think that spraying them with high heat paint is the only option and i'm not even sure how well that will work with the high heat and excessive moisture it will be exposed too.

 

The majority of anti foul adapters are aluminum, you don't need to paint them or do anything to them unless you want. The other thread posted today the guy is using plumbing pipe hardware for his, I'm not knocking it. It will just rust very badly if its not painted.

 

bringing back an old thread... has anyone eliminated the rusting issue for this mod?

 

there should be no issue with rust as most of the connectors are all aluminum.

 

Update...

Still no CEL, 10k miles since I installed the simulator.

I too would like to know this

 

I tried this and it didn't work for me. I had to install an 02 simulator to fix my problem.

 

I just went to get the adapters and the 42009 is the one that should work. hopefully

 

Yes... I got the non tapered, 42009 adapters also. I've had it on now for a week, so far no SEL. I was only able to use one adapter because of the catback bung being angled. We shall see.

 

Hey you're a saviour timzcat!

 

Yea man. I've had mine in for a week and no CEL

 

I have an RMR 3 inch turbo-back exhaust. For street use, I put the stock catcon back in. For the track, I install a straight pipe. I installed two of the adapters in the spring to space out the O2 sensor.

I occasionally get the CEL coming on with both the straight pipe and the stock catcon, but it is only when cruising (constant speed) at about 95 mph. When this happens, I disconnect the battery to reset the ECU and the light goes a way. It is a bit of a pain, but seems to work. It's not too often that I get to run at a constant 95 for a few miles!

Anyway that is my experience with this fix.
