spark plugs..im an idiot

[LT]

im trying to search the fourms for spark plugs. ive search spark plugs...ngk all kinds of thinks. i know the fourms are out there. but im gonna try running some ngk iridiums. NGK BR9EIX Iridium...that the right plug to run in a 09 assault 800

 

[jim9006]

yes..

 

[LT]

yes..

thanks jim!!!

Hey everyone. I believe the correct NGK plug is a BPR9EIX or BPR9ES.

Hey everyone. I believe the correct NGK plug is a BPR9EIX or BPR9ES.

That is correct. Make sure it has the "P"

 

[mountainhorse]

Yes...Monte is correct!!

The BPR9EIX in the Iridium....

Other "P" plugs (projected tip)... like the BPR9ES or the BPR9EV also cross.

From Polaris Industries
Use Champion RN57YCC or NGK BPR9EV gapped at .018”

Summit racing at $8 each.
Oriely (Kragen/checker/shucks) wanted over $13 each (non stocking item)
NAPA has them for $9.19 (Click Here)(non stocking item)

There is also an NGK dealer that I've used from eBay that takes papal. (top seller)

$7.75 each with cheap shipping/handling (about $5 in the usa)

CAMPNOUT@COX.NET is his email (ships from Las Vegas)

 

[mountainhorse]

I just got an email back from the Vendor that I've purchased from in the past...I asked him for a shipped price to the USA...

For the NGK-BPR9EIX plugs

If they contact me directly at CAMPNOUT@COX.NET I will do 7.40 each and 5.00 priority for up to 16 plugs. They have to mention " ERIC- FORUM" for this price.

For Shipments to Canada the cost of shipping is $5.20 via first class mail... plus $2 mandatory insurance ($7.20 US dollars)

what happens when you run a br9eix instead of the bpr9eix??

Not good things......Run the right ones. The reach on them is longer.

 

[crf118r]

Do these actually work better than the stock Champions in the Dragons?

 

[Klutch]

What are everyone gapping their plugs at, .018" as per polaris instruction, or something different? What about the iridium plugs, what do you gap them at? Thanks

Did you already buy the BR9EIX's??

The projected tip ("P" in the BPR) .... affects how the sparkplug ignites the mixture in the combustion chamber...

It also greatly affects how susceptible the plug is to low speed fouling..

The RN57YCC Champions that are the OEM plug are also a projected tip.
The "Y" in the YCC stands for Projected tip.

Here is some more information on the Iridium spark plugs.
http://www.spark-plugs.co.uk/pages/technical/iridium_spark_plugs.htm

One very useful variation of the standard spark plug has its insulator nose and electrodes extended from its metal shell. The projected-nose configuration moves the spark gap a bit farther into the combustion chamber, which tends to improve efficiency by shortening the distance traveled by the flame front and also making the combustion process more regular. But there is a more important benefit: the projected-nose plug provides, in many engines, what effectively is a broader heat range than you get with the conventional flush-nose type. The projected nose is more directly exposed to the fire in the combustion chamber, and quickly comes up to a temperature high enough to burn away fouling deposits after ignition occurs. Then during the subsequent intake phase this plug's exposed tip is cooled by the swirling air/fuel mixture. In this fashion the higher temperatures existing at full-throttle operating conditions are to some extent compensated by the greater volume of cooling air, and the net effect is to make the projected-nose plug better able to cope with the conflicting demands of traffic and highway travel.

Did you already buy the BR9EIX's??

ya i already bought the br9eix's! i ran them all yesterday. i guess i'll take them out run the regular ones. hope something bad didnt happen

 

[zitterich246]

I bought the BPR9EIX plugs off amazon.com at $7.40 a piece and if you buy 4 its free shipping. Also you do not need to gap the irridium plugs

 

[mountainhorse]

Great lead... I just orded 4 of them... free shipping (over $25 in the USA)... can't beat that!!

Thank you zitterich246

The Iridiums are always worth the money....you get what what you pay for!!!

What is the benefit? Longer life? Improved performance?

 

[05900]

Noticed easier starting,have yet to foul one and I dare say throttle response but would have to attribute that more to the intake also. Keep an extra set in the bag and almost always lend them out rather than use them.

 

[milehighassassin]

Just bought a set on amazon today. Kinda funny, did so before reading this thread. I was going to say amazon an someone beat me to it.
