I have an 08 S2k and I installed a Berk header back exhaust and after about an hour of driving the CEL went on. Need some options on how to get rid of it. Thanks

 

Probably need to pick up a spark plug defowler. Stick the secondary o2 sensor into it to space it further away from the exhaust.

 

I have read that the spark plug defouler doesn't work for 06+ s2ks and where the cat is suppose to be, there's a 2-3" built-in CEL fix, where the o2 sensor goes. How much further should the o2 sensor be away from the exhaust? Here is a link on what the built in CEL fixer looks like. http://www.berktechnology.com/produc...with-test-pipe

 

I too have an 06 I had to use the j shape defouler. Sold by evasive vibrant t1r or I got mine on club rsx. I had issues with 3 defoulers. The j cured it

 

Here is what worked on my 00-05 car, it may or may not work for you, but for $13 it might be a viable option to try.

Thanks for the reply backs. My flashpro is coming in soon and I just read that I can turn off that 2nd o2 sensor, I'll do more research once the device is delivered. Evasive vibrant t1r defouler is ~$50.00 not including shipping, really pricey. Hopefully there are cheaper J-Shaped defouler options. Man, I can't wait till this flashpro gets here...

 

If you can turn it off with the flashpro, just do that.

 

CEL fixed. TY Flashpro

 

FYI, you can get 2 of these at AutoZone for like 4 bucks. You can stack them together (just drill one out with a 1" 1/2" bit).
