Features: extender tube keeps the heat away from the flexible tubing, the only one on the marker like this. since the tubing stays cool it allows permanent installation, not temporary, this is great for use with Engine management systems that use Exhaust back pressure as an input parameter (Autronic etc) steel tubing, conducts less than copper and has highest fatigue life to resist vibration. "clock able" fitting designs allows orienting the tube in any rotation. tubing is annealed so that it can be bent as needed, multiple times. includes adapter fitting for oxygen sensor, heat isolating extension tube (straight!) . adapter fitting fits all 18mm oxygen sensor bungs (MOST cars have this size fitting,some jet ski's and some late model motorbikes do not. includes a spare (pre curved) bung(not shown) and plug, in case your exhaust does not have an existing bung. You can also order a stainless steel bung separately if needed. The sensor adapter has a calibrated orifice to minimize needle fluctuation from exhaust pulses. (not necessary but a nice feature). Can also be used to measure other pressures. No, the exhaust pipe is not included. Shipped via priority USPS flat rate small box. Show more
