Spark Plug FAQ

bigg_vin · 10-13-04, 22:31

hi
i just changed my spark plugs, and REPCO did not have what i thought were the right plugs. i ended up buying NGK plugs, the step down from the irridium ones, (cos i couldnt fork out 22 bucks a plug!!!) the model number is ZFR5F-11 are these ok?? also, i have been tols that u can see the piston head after removing a plug, HOW? i could not see S***!!! i think i have the KLZE, but then i read that they use different oil filterz??? wats teh REPCO spec that the KLZE needs if the KLDE is Z411??? thanks

Yes you can see the piston after you remove the plugs, but you will need a torch. You won't see much anyway so why bother. NGK plug are pretty good.

The KL-ZE uses the same parts as a KL-DE such as plugs, oil filters, etc..

I think manufactures only spec iridium because they can last 100000km. The rear bank of a FWD V6 can be quite a difficult to access, so the less times you need to change them the better. I'm sure the V6 Camry specs iridium for the rear bank only. No idea about Mazda.

Make sure you properly gap the plugs before you fit them.

You should use the BKR6E 11 or a BKR5 11 in your ZE, you will find they are from an MX5 in Australia

I occasionally squirt Nitrous in to my ZE so I use the colder BKR7E 11 plugs..

The ones you have are a (5).. but the wrong design (longer)..same dimensions as the KLO3 uses..

you can use a 5 or a 6, on regular unleaded it would run better with a 5 .. but if you use PULP use the 6...

To “GAP” is the term used for setting the distance the spark jumps (intensity) you do it by using a feeler gauge between the 2 surfaces…

Thats probably something for the Aussie FAQ's.

Nice post MrMX6

You make it sound so innocent, LOL.

am i damaging my enigne using the 5? i only use premium unleaded. i rang repco, and they said that the mx5 ones are cheaper, can i get irridium ones for hte numbers u quoted? thanks again

**Mr. MX6** · 10-15-04, 4:53

There are 2 different mx5 plugs depending on the year .. you want the ones from the 89 and on 1.6 ltr (BKR6E 11)

The iridium ones are BKR6EIX 11

with the 5, No actual damage .. but performance will be a bit off..

hey i jsut changed myne today
remember to use anti seize and make sure you gap them properly at .39-.43 any more or less and it can screw the fuel economy, also do an inspefction of the spark plug wires as well, i changed myne over today ($150)
the DE takes NGK ZFR5F-11 or motorcraft AGSP 33C (up to 1998)

i had good tools so it was easy jumping into the back ones, so in this case i will be changing them relativlly often so i wasnt going to waste my money on irridum ones because i will change them often enough, i would never leave it to 100k, so screw $22.

if you have trouble getting them startedtry using a piece of rubber hose, that helped me, it should grip well onto the spark plug so you can turn it, you should do a quick ass visual check on your distributor as well for cracks and carbon tracks etc.... beacsue that could be costly if you leave it.

With the spark plug wires look for sparks and cracks and [shizzle] while the engine is running, but make sure its cool before you change spark plugs/wires

Also if you are [fizzle]ign with the wires remember to number them or do them one at a time dont mix them up, if there is a lot of corrosion (white powdery stuff) then you might need to invest in some new wires (also dont bend the wires - it will snap the conductors)

**Mr. MX6** · 10-16-04, 17:58

Good advice . I have never gone for iridium plugs either better to replace normal ones occasionally.. And with the grabbing of the plug you can get sockets with a rubber insert for griping the removed plug.. or just cut a section of hose and stick it into the socket you already have…

And.. If you do require some wires (bit late for you mix master).. Look in the forsale section.. only ~ 50 bux from the shiny suit man.. .
