Plugs for 87' lazer xri

[brade07]

I have a question if anyone knows of different plugs available for this motor. At my local auto parts stores and marinas i can only find NGK and they are $16.00 a piece? It cost me around $100.00 bucks with tax for a set of plugs.

Any help with this would be appreciated
Thanks
Braden

They are giving you the price for the resistor plugs. I'm pretty sure the 2.4 EFI is analogue not digital and therefore does not need a resistor plug. The standard NGK shouldn't be more than $5. I run standard plugs in my 2.5 EFI without any problems. If the resistor plug for a 2.4 is a BUZHW(double check to make sure), the non-resistor will be BUHW.

Check this place out.

I also ru non-resister plugs in my 2.5 efi with no problems.

The NGK web site has them for $2.49
The only other cheep place I found was rickracers $2.99

Alrite i checked out the NGK site, It shows i need the resistor plugs, but you guys think it will be ok without them?

It was a Merc dealer told me the Optimax and newer EFI's must use resistor plugs because they have a digital ECU. The older ones are all analogue and will run fine with standard plugs. I have run both in my 1992 2.5 200 EFI and did not notice any difference. The other reason you might run resistor plugs is you are running a bunch of electronics on your boat that could interfere with the ignition. Usually resistor plugs are not much more money. The NGK resistor plugs for my Yamaha are only $5 each. For some reason they hose you for the ones for the V6 Merc. Who wants to drop a C-note every time you change plugs?

Well i do have a fairly big stereo running 6 speakers the head unit an amp and a sub, but other than that just a depth finder.

Heres the scoop as far as i know:

you use resistor plugs in an engine to reduce interferance with electronics and stereos. Using a non resistor plug may also cause havic with pacemakers. In every motor box we got at the marina came a second set of plugs which were resistor. In Canada we were required to switch the plugs to resistor type. As a dealer we were supposed to sell the resistor plugs only. 100 bucks isnt that bad for a plug change considering you do it once a year. an optimax takes $30. plugs and they need changing every 100 hours or so (or about twice a season). So thats around 400 a season for an opti owner.

Keep in mind also that the surface gap plug you are using are limited in production compared to BR6FS plug for a 350 V8. They are only used in marine applications as far as i know.

Hope this helps a bit.

Go with Chris on this one. He would know.
The fishfinder is no big deal, but with all that stereo gear, I would stick with resistor plugs. The electronics on an EFI is very sensitive. Even a weak battery can make it act up.

So Chris, why do you think the resistor plugs are only required in Canada?

Honestly, i'm not sure - no one has ever given me a great answer, but i believe it has something to do with the pacemaker issue (you no, not wanting grandpa to keel over in the tin boat when grandson starts the motor - that kind of thing)

As mechanics, we were only ever supposed to put in resistor plugs, which most are anyway. Some of the resitor plugs are outrageous in price though, and that i can only blame on economies of scale and lack thereof. I checked everyone accross the country on opti plugs (pzfr5h-11 or something like that) and everyone was the same price give or take a $1.00.

??????? $100 for 6 resistor plugs!!! http://checkmate-boats.com/graemlins/sick.gif
"Resistor" as in "I resistor in buying them"??? http://www.checkmate-boats.com/infopop/emoticons/icon_razz.gif

What are they made of??? "UNOBTAINIUM"??? http://checkmate-boats.com/graemlins/lol.gif

I'll make a phone call to my buddy in the parts business... I'll see whats up with that!
NGK, Bosch, Champ's... someone has to make something for less than $100 a pop!

[brade07]

gotta remember this is in canadian dollars though not US. You could probably get them for around 60-70 in the states, or thats around what they are from NGK.

[jrumon]

OK... the low-down so far.
The correct plug for the 220 Lazer efi is the NGK #BUZ8H and they are an "inductive resistor" surface-gap spark plug.

I would say not to mess with non-resistor plugs. I didn't have a chance to interchange them into any other brands yet, but they are sold wholesale in a box of 10 for around $50(us) per box... Ouch!

I'll try a cross reference as soon as I have time just for kicks! Jim.

Alrite thanks for your help.
even if i could get 10 for $50 US, thats still alot better than $90.00 CDN roughly $80.00 US for 6.
