Default NTK 21537 instead of Bosch 13111

So in light of all the complaints about the Bosch and Denso o2 sensors I decided to try the NTKs (same company that makes NGK spark plugs). The 21537s are for Corvettes and they're long as hell... over a yard long as you can see in the pic.

Hopefully they'll do a good job. Anyone else have the NTKs?

I had all kinds of o2 problems when I did my lt's. My extensions always got wet and missed, so I went to 13111's and after 2 months they threw an ses code for slow switching or something like that, so after fighting all that I decided to grow a pair and repin my pcm for the rear sockets to read the front. Worked perfect. No more ses and I can use factory length o2's and not 10ft Vette sensors.

^ That's what I wanted to do, but my cheap eBay headers have the bungs for the sensors on the wrong side. As a result the stock 02s aren't long enough to reach the rear sensor harness.

ive been wondering this too. i havnt had any problems with my bosch 13111's up until now which has been about 3 years since i install my lt headers. im in the market to replace mine and was wondering how the NGK's stack up as well. their spark plugs are great and the wideband kits are good too i hear.

Have had the NTK/NGK vette ones for a little over a year and no problems but the typical switching codes every now and then.
