NGK Extended Reach Spark Plugs

[LinuxRacr]

The ZFR7F-11 could foul out faster in colder weather. I used them all winter here in Texas. Lowest it got was 20* F outside last winter.

Alright I was looking through Crossover Auto Performance's Site and saw three different plugs. I have a MSP with a 3" catback and possibly getting the GHl downpipe.
I just want to know which one would be good for my car, I'm not sure if i will be turning up boost right now. Considering I don't have enough for a FMIC of my choice...

NGK Iridium Spark Plugs

• BKR7EIX-11
• 1 heat range colder
• Recommended for race applications where engine is constantly revving high under high boost levels
• Will foul out with low rpm daily driving
• Set of 4

---------------------------------------------------------
NGK Iridium Spark Plugs

• ZFR6FIX-11
• Stock heat range
• Recommended for street use
• Set of 4

-------------------------------------------------
Denso Iridium Spark Plugs

• IK20
• Stock heat range
• Recommended for street use
• Set of 4

-----------------------------------------------------------
So which ones would be good, to smooth oout idle and during acceleration and to help stop the bogging??

So are there any plugs if the ones I posted up top aren't.
Are there any ones that are irdium from NGK or Denso that are one stock heat range cooler?? The first plug I listed above says it can foul out if its run like normal everyday. The reason i don't want to get coopers is because they won't last as long as the Irdium or Platnum.

Don't waste any money on the Iridium or Platinum plugs... they will foul easier (although you don't sound too modded.. so it may not be an issue) and there is no real performance gain over them. If you are dead set on extended reach get the NGK ZFR7F plugs, or go like most of us use now - the NGK BKR6E both of which types of plugs will run you about 2-3 bucks each and will last a good 30,000 miles or more.

What's the Difference between the two u mentioned? And are they copper?

I can find them at an auto zone or somethng close right? And they aren't extended reach??

 

[TurfBurn]

The ZFR7F's are extended reach.. both numbers listed are copper.. the only difference is the extended reach. You can get them from auto zone probably, otherwise sparkplugs.com can get them to you in under a week.

 

[Notorious_V.I.C]

So most people are using the NGK BKR6E now??

But aren't they stock heat range??

or are the NGK ZFR7F stock or one step colder??

Oh and do I really need to replace the stock spark plug wires???

 

[TurfBurn]

Stock heat range is BKR5E... anytime you go extended reach you need to go one step colder... so a an extended reach heat range 6 is the same as a standard reach heat range 5... The 7's are one step colder than stock... and same with the BKR6E being one step colder than "stock" (2.0 ES's and so forth run the BKR5E plug)

Im using iridium NGK BKR7EX-11

I agree with turf on this one. Get the BRK-6E's. That is ALL I have ran and since it is the stock type plug, you don't need to worry about some of hte BS I have heard and seen about other plugs. They're in-expensive and last long enough. Why go with those more expensive plugs, they don't give you any gain and people who say they do are full of it.

This is what some of them "fancy" plugs can do. So it's better to stick with the type that the factory does, just 1 heat range colder though!!!

 

[Notorious_V.I.C]

I can't find the NGK BKR6E on the sparkplugs website. And is that the right one that I typed in? I jst want to go one step colder and it seems like this is the one to go with??
