spark plugs for qg 15

[grasshopper4389]

what types of spark plug should i use on a qg 15 engine i have bkr5e-11 is that a good plug because there is a carbon build up just wanted to know if i need to change to a hotter plug may it be the bkr4e-11???? i did some research and got the pluge diagrms but no part number to work with

[eitech]

stick with bkr5e 11..dats d recommended plug in d manual

if its a heavy carbon build up on the plug, its not the plug your engine may be running rich using a hotter or different plug wont help that
best you do a full service cleaning throttle body, maf sensor, engine flush etc then change your plugs

in our climate, especially if the base of the ceramic on the plugs is browning quickly, it would be safe, even recommended to use the NGK BKR6E-II

[cool]

i agree with wagonrunner--i use ngk bkr6e11 it is a cooler plug and works well .don't use the hotter bkr4e11.

the reason i ask is that the muffler is black and i does run about 120 average every day from port of spain to princess town ,at least it should be brown.I know i may be looking for the traditional white you guys every saw white or even brown???in the morning when i start i get the water coming out ( condensation) and drops of black i mean it does blow out why the black as slow323 indicated there is black carbon build up on the plugs i did a clean up of the throttle,injectors etc whats the problem???

Use BKR5E or BKR6E..............DO NOT USE BKR4E

I experienced that situation already (still am)...I don't know what is the cause but i never really looked into it. (I use Irridium BKR5E IX btw)

It never bothered me in no way...i would clean the barrel out when ever it got blacked or dirty.

you ever cleaned your intake manifold, i see many guys just clean the throttle body and neglect the intake manifold

also what oil body and type are you using

[QG]

I never cleaned Intake Manifold...just Throttle Body.


I using 20w 50....OIL is very blackk though...i haven't had an oil change a long while now

[grasshopper4389]

i does use shell 20w 50 as well change it every month as well as oil filter and air filter so it clean .

your internals clean but probably not your intake manifold, disconnect the tube from your pvc valve, spray inside the manifold with your choice of carb/throttle body cleaner let it sit for half hour.
re connect the tube and start up you will see a lot of white smoke but take a spin around and that will stop
believe me i thought mine was clean also and i change oil at 3000km

I hear Bars good to use to clean throttle body and Intake Manifold....I will try doing the method you mentioned.

[slow323]

yeah try and see before you change the oil, is good practice to change the oil after you do the cleaning

[QG]

True, that's a good advice there...I never even thought about that

[TRD...all the way]

Check Your O2 sensor !
