*Don't fall for the bigger Mamba 3/4" (19mm) hose trick!

*REALISE that 16mm (5/8") is as large as you can go for uniform flow, due to Tee connector and OEM heater hose sizing restrictions!! CHECK Bti QUALITY to compare!

#AUSTRALIAN BTI 2023 Version 4 KIT

SUITS ALL EJ20/22 AND EJ25 SERIES SUBARU 4 CYLINDER BOXER ENGINES-

ALL N/A OR TURBO MODELS UP TO- 2014 liberty, forester & impreza

-ALL STI GC/GF TO 2021 STI

IT IS A WELL RECOGNISED FACT THAT THE SUBARU 4 CYL EJ SERIES ENGINES HAVE HAD A DESIGN FLAW WITH THEIR COOLING SYSTEM, THAT ALLOWS A CONCENTRATED HEAT POCKET TO FORM OVER #4 CYLINDER

THIS FLAW  HAS OFTEN BEEN ATTRIBUTED TO  RING-LAND FAILURE,

KNOCK & DETONATION IN THE  E.J SERIES BOXER ENGINES

THE BTI D.I.Y KIT WAS DESIGNED TO CORRECT THE COOLANT FLOW 

(SOMETIMES REFERRED TO AS "REVERSE")  VOLUME OVER CYL #4 ON

EJ SERIES MOTORS

THIS REDUCES CYLINDER #4 COOLANT TEMP WHICH IN TURN LEADS TO A

MORE UNIFORM TEMPERATURE ACROSS ALL OF THE CYLINDERS

( **TESTED TO SEE UP TO 10 DEGREES REDUCTION IN OVERALL HEAT DIFFERENCE BETWEEN L & R CYLINDER BANKS PRIOR TO FITTING OUR KIT )

This KIT is a must have for those wanting, what is definitely cheap insurance, for

PARTICULARLY TURBO EJ engines
