Lambda Sensors

After reading up on the Innovate Lambda sensors Wideband Controller, I decided to add some length to the exhaust bung to make it the 1" as instructed.

As supplied by GD, the bungs were approx 10mm deep.  I found some stainless steel ones on eBay that were 21mm long.  I put them in the lathe and turned them down to 15mm to give me the overall required 25mm length.  A friend then TIG welded them onto the top of the existing bung.

I had to remove the exhaust to be able to do this, and once welded, the exhaust was replaced.
