## Questions & Answers

**Q: does it help to ready the catalyst sensor if you dont have cat on your car?**
A: YES, I have these fitted to numerous cars that run aftermarket self tuning EFI systems with zero cats fitted. They definitely extend the life of the O2 sensor plus assist with smoothing the AFR readings. Just my observations & experiences, well worth fitting them.

**Q: Does it also work with 4.9?**
A: Yes it is working well

**Q: Does this include 1 or 2 ?**
A: 1 only

**Q: I have a porsche 2001 911 i put new o2 sensors but still the check engine code comes up would this help**
A: If you are killing the o2 sensors then yes this could fix that issue if you are sure it is the o2 sensors that are dieing that are causing the check engine light.

    Great piece of kit
  

*by A***R on Reviewed in the United Kingdom on 2 May 2016*

Great piece of kit. Used in my 540ci marine engines to keep the 02 sensors dry. Works a treat. I needed to get additional shims to allow the air input hole to face the exhaust stream when tightened up.
