ISSUE: Deposit resistant injectors (DRI) have two (2) unique features which are tolerant to deposit formation. The DRI's are tan in body color (not connector color) and do not require cleaning.

ACTION: No cleaning action is required for deposit resistant injectors. The two (2) unique DRI features are:

^ The Bosch (DRI) meter fuel through a 4-hole director plate.

^ The Nippondenso (DRI) allows a wider tip opening by metering the fuel upstream with an internal orifice. The wider tip allows a deposit buildup which does not affect the fuel flow and vehicle function.

NOTE: THE PINTLE-TYPE INJECTORS USED ON EARLIER MODEL YEAR CARS AND TRUCKS MAY HAVE DEPOSIT FORMATION AT THE PINTLE AND SEAT AREA. THESE PINTLE-TYPE INJECTORS ARE BLACK OR GRAY IN COLOR. THEY MUST BE CLEANED WHEN REQUIRED BECAUSE DEPOSIT BUILD-UP CAN AFFECT PERFORMANCE.
