#2003 MAZDA PROTEGE 5 SPARK PLUGS LOCATION SERIES#

This places the electrodes closer to the center of the incoming A/F mixture with apparently beneficial consequences for power production.

The two series of plugs have identical characteristics with the sole exception that the plugs for the 1.6 L engine have an extended projected tip. Spark Plug Substitution in the FS-DE Engineįollowing the recommendation of TheMAN, some of our Forum members with the 2.0 L, FS-DE engine (myself included), and the 1.8 L, FP-DE engine have replaced our spark plugs with those used in the 1.6 L, ZM-DE engine. Recommended as the performance plug of choice in street applications.ĭenso KJ16CR11 Original U-Groove, alternate OEM fitment as listed in the FSM.Īrranged in order of least to most expensive, the above five spark plugs have a reach (threaded length) of 19 mm (.750') are pre-gapped at 1.0-1.1 mm (.040'-.044') have a heat range of 5 (or equivalent) and an extended projected tip.ĭenso K16PR-U11 U-Groove type, alternate OEM fitment as listed in FSM.Īrranged in order of least to most expensive, the above six spark plugs have a reach (threaded length) of 19 mm (.750') are pre-gapped at 1.0-1.1 mm (.040'-.044') have a heat range of 5 (or equivalent) and a projected tip. 4 mm diameter U-groove niclkel alloy ground electrode. Iridium Power: Laser welded fine wire iridium tip center electrode. Longest sevice life of all Denso's plugs. Iridium Long Life: Laser welded fine wire iridium tip center electrode. By opening up the space between the electrodes, without increasing the gap, quench is reduced to a considerable extent.ĭouble Platinum: Platinum tip center electrode platinum ground electrode. Platinum tip center electrode, 1.1 mm diameter rather than being flat, the ground electrode's firing pad is a free-standing titanium-enhanced tip. Platinum TT: The TT stands for twin-tips. OEM for all proteges listed here except the MSP.

Original U-Groove: Nickel alloy center electrode U-shaped nickel alloy ground electrode. Its iridium/platinum surfaces give it the longest service life of all NGK plugs making it an OEM approved design.

Laser Iridium: Laser welded iridium tip center electrode platinum disc welded to backside of ground electrode. Because its platinum surfaces ensure a slow wear rate providing a longer service life, superior anti-fouling, improved fuel efficiency, and lower emissions, it is an OEM approved design. Laser Platinum: Laser welded platinum alloy tip center electrode platinum disc welded to backside of ground electrode. 6 mm diameter nickel alloy tapered ground electrode designed to minimize the 'Quenching Effect.' As a consequence, NGK recommends this as their performance plug for road cars. Iridium IX: Iridium tip center electrode.

6 mm diameter nickel alloy ground electrode. G-Power: Platinum alloy tip center electrode. OEM for all Proteges listed here except the MSP. V-Power: Nickel alloy V-grooved center electrode nickel alloy ground electrode.
