NTK sensor alone is very expencive like 170 from what i found. And boish is around $50. Question is how long will ntk sensor last before replacement?

 

The Ngk sensor is far superior to all imo. That is the reason for the higher cost. I love mine.

 

Be aware you have to match the sensor to your wideband controller. You cant mix and match as far as I know.

 

what brand wideband do you have? most use the Bosch LSU sensor. AEM seems to use the crappiest one.

 

im looking to buy one, i wanted to know the lifespan of both sensors.

 

aem is 225 and ntk is 250. for the kit.

 

The AEM one uses a bosch sensor

 

Yes the NGK is prolly the most accurate i have seen. The sensor last quite awhile.

 

Holy crap I can't stand it anymore.

NTK Not NGK. N ******* T ******* K. ****.

The bosch sensors have a bad rap but they're not that bad. They are slightly slower to react then the NTK sensor. Accuracy and lifespan have many factors other than simply which unit you buy. Bad placement can cook a sensor really fast, especailly on a high EGT rotary.

 

Are they both accurate to 0.1?

 

NTK is made by NGK not big difference

 

Yes, they're both accurate. The system is important as well as placement. Example, I've heard people curse the AEM setup since it uses a bosch a sensor. The same person says they prefer an LM1 because it has free air calibration......but it still uses a bosch sensor.

If I were to purchase another WB setup I would buy an NGK AFX that uses both NTK And Bosch sensors. You could do some decent testing but either way, either sensor should yeild accurate readings but the NTK sensor will react faster.

Where should sensor be located on the header on n/a application?

 

right after the collector would be best.

 

I do like the fact that it is free air calabration. The lifespan has alot to do with howthe car is tuned, placement, gas used (race fuel) etc....

 

Buy an LC-1. It has a quicker response and costs about the same or less if you need a gauge they have cheap and nice datalog style ones at www.moates.net. My brother in law uses the NGK the response is absolutely ridiculous not to mention how slow the LED's read.

 

im running a true dual with no collector, is there recommended length from the motor?
