FR7DTC is Bosch model.
Copper core, triple electrode.

RM15/pcs.

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.

Added on November 7, 2011, 11:18 pmNGK BKR6E-II is also used in Waja 1.6, RM8/pcs only. But the gap is different from Bosch FR7DTC, so not recommended actually.
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.

Denso IK20 is iridium core. Got member selling a set of 4 for RM130-140 at Automotive Garage.

BKR6E-II, if u dare to try, it may work fine or it's not suitable. U just risk RM32 + labour. If it works, then u'll save in the long run.

bladekiller, ur old plugs look still ok.

felt any difference after changing to Denso Iridium?

When I 1st changed from Bosch Super 4 to Bosch Plat-Ird Fusion, I can really feel the car more responsive & better pick up. Plus consumed slightly less petrol.

BUT, it only lasted like 20000km, then it's like back to b4. At 60000km, I took the Fusions out to inspect, bcos at that point, my car would need 2-3 cranks in the morning. I can see some irregular trails of spark, the Fusions have 4 electrodes, so there're 4 trails, some the trail is weaker than the other.

So I decided to swapped them back to the OEM spec FR7DTC. FC slightly higher than on Fusion, but it also could be due to I'm now running 200kpa tire pressure compared to 220kpa previously. But in the morning, 1-2 cranks enough to get the engine running.
