[raufnadeem516]

@adeel,

sorry do'nt know about bikes.

@alikhan,
Denso K20RU-11 is ideal or Bosch FR7DCX+, Heat prob cause u install wrong heat # plugs.

@Raja,
U canb install BKR5EGP-11 or BKR5IX-11 best is DENSO IK16.

@Devil,
In mehran CNG W16EXU is best.

I have a honda city Exi-s Auto (running on petrol) and its 1300CC i dunno anything about valves or cylinders exactly could you please recommend me something, i used to have the same manuall model on CNG and was using FR78X BOSCH SUPER4 they were excellent both in fuel economy and performence...

[raufnadeem516]

@aantherax,
You can use Bosch 4 tips FR78X in ur Automatic city (petrol)also, same engine 4valve/cyl like ur manual, should check & adjust valve's tepits also.

sir one more question, installing those plugs will increase fuel economy in auto as well because they made a noticable diffrence in a munuall one... and yes without any tappet adjustment or anything.

[aantherax]

and is there any way to find out if they plugs are orignall german made or the fake chinese ones ?

[raufnadeem516]

@aantherax,

No,chinese u should go to good shop like Optima ph:021-5868451
Mr.mohsin, u can choose Autolite paltinum AP3923 made in U.S.A
remm good plug give not only smother engine also good fuel economy if engine runs roughly economy also suffer, do'nt change any gap setting on new plug.

i have cultus vxr...want best performance in pick on cng n petrol..
what is your preference for cultus ( not efi) ?
n whats the price of these plugs?

[asadi13]

wat do u recommend for vitz 2004, currently i have NGK iridum plugs installed but not satisfied as im not gettin a very good fuel economy. My car is on petrol.

[raufnadeem516]

@badblue,
In cultus geniune # is Denso w16exu, try denso's k16ru11, or bosch fr8dc.

@asadi13,
NGK Iridium is very good plug, i think ur car suffer some other problem, check to an good mech may oxygen sensor trouble, clean it with carbrator cleaner spary both plug & sensor,b carefull about plug's tip.

[aslakho]

sir which plugs also price u suggest for 1.3 xli 2003 (cng) for economy & pick up

[raufnadeem516]

@aslakho,

In Corolla best in price & performance Denso K16RU11 each may b Rs.125ea, further Bosch 4tip FR78X set of 4pc Rs.1200 or FR8DCX+ may Rs.150 ea, (tip gap geniune should b 1.1mm) all these works best in 1300cc 2NZFE CNG.

@rauf

i was thinking of installing NGK BPR5EIX in Alto CNG, what is your opinion?

[autobanda]

BTW do you guys stock high intensity Halogen Bulbs like the Philips X-treme Power Halogen Bulb, if not then can u or anyone suggest someone who does?

[raufnadeem516]

In Alto u can b Install NGK Iridium, but Bosch 4 tip# 503 may give u better result, this is very low out put engine so do'nt spend much money on plugs, for HID contact Mr.Nadeem ph6375072.

[Hassan_2005]

plz suggest me for cuore cng .. dun 25k .. iz there a need for changing plugs ?
if yez which one bosCh 4tip wud go okay
plz helP
drive mostly in city

[raufnadeem516]

@Hassan_2005,
In cuore, plugs should change after 25k, Denso K20RU11 is recommended, further Bosch 4tip or Bosch 2tip# FR7LDC+ works better in CNG.

plz suggest me over installing BOSCH SUPER 4 510 in Alto VXR CNG 2005... the person at the shop said they'll be fit for ALTO however you've suggested 503... what reallly is the difference n should i go for the 510s

[raufnadeem516]

@cooolsatan,
Bosch 4 510 FR78 X is for corolla or civic cause gap setting is for those cars, X means 1.1mm gap, so WR78 503 gap setting is for suzuki or smaller cars 0.9 gap setting, so install WR78 503 or FR7LDC+ two tip plugs.

[mallic]

suggest me plugs for Civic VTI 04 model?
