QUOTE 14mm Thread Size, 19mm (3/4") Reach, 5/8" (16mm) Hex Size, Gasket Seat, Interference Suppression Resistor, Yttrium Enhanced Copper Core Center Electrode, Tapered V-Profile Nickel Ground Electrode, Removable Terminal Nut, .035" (0.9mm) Gap, Heat Range 7 Bosch Super Plus spark plugs feature a heavy duty yttrium enhanced copper core center electrode for superior reliability and increased resistance to spark erosion. The tapered, v-profile nickel ground electrode provides improved starting in cold weather and increased fuel ignitibility. The metal glass fused resistor allows for maximum interference suppression while the ribbed insulator design prevents misfires due to current leakage. source same as wat u found? btw this is the replacement model FR7DC+ i don't get what u r trying to say cos u mentioned triple earth electrode in your earlier post.

FR7DTC still in production lah.  But mainly used by conti cars, so normal spare parts shop may not have it. I just bought 4 pcs last month. Made in Germany stock.

NGK BKR6E-II is also used in Waja 1.6, RM8/pcs only. But the gap is different from Bosch FR7DTC, so not recommended actually.But I got this result in another forum.... Factory install : Bosch FR7DTC (Triple earth electrode) Some alternatives BOScH FR7DC, FR7DCX etc Denso K20PRU-11,K20PBR etc (normal),IK20 (Iridium), VK20 (Iridium/Platinum) NGK BKR6E-11 Instead, BKR6E has similar gap with FR7DTC. Other Bosch cross ref for BKR6E - FR6DP, FR6DC. While the cross ref for FR7DTC - NGK BKUR6ET or BKUR6ET10 (multi-ground), Denso K20PBR. This post has been edited by scorgio: Nov 7 2011, 11:19 PM |

Apologies to TS for 'borrowing' his thread.
Wanted to ask the sifu's here. For a Iswara LMST what plug is best suited to get that extra 'kick' during driving without effecting the FC too much? Currently running on original plugs and cables. |

Some mention smoother pick up with Iridium but they cost RM150 or more per set.Wanted to ask the sifu's here. For a Iswara LMST what plug is best suited to get that extra 'kick' during driving without effecting the FC too much? Currently running on original plugs and cables. Probably you can try a set of platinum first. Different material are actually more for durability, means like using platinum will last longer then using normal plugs, and Iridium even longer. Now they even have Iridium tough..... But then using cheaper plugs you can use many sets so back to square one......

Ya top of engine block is dirty. Some oil stain, looks like very long adi. It's near the inlet where they pour the engine oil.
Y ah? Might it sip through when changing the oil? |

Yup, should be. Try cleaning around that area, but with the plugs on, in case some dirt fall inside.
If internal problem the plug tip will be oily...... |
