Wanted to know if anyone who using the lingenfelter box to pull timing runs non resistor plugs? Can not find any resistor plugs colder than a 7, and lingenfelter recommends running resistor type only.
Thanks.

 

Lingenfelter recommends using the resistor type plugs because the non-resistor type can cause interference. We have had great luck with it and never ran into an issue with the NGK B8EFS and other plugs, but you want to use some good noise suppressing plug wires with it.

 

Thanks for the response. Any recomendation on the wires?

 

The TR7 plug is roughly the same heat range as the Denso IT22 plug.

Staying in an NGK plug a TR8ix exists that is one heat range colder than the TR7 (and the TR7ix which is the NGK iridium version of the TR7).

IT24 and IT27 resistor type spark plugs are available from Denso.

The IT24 is similar in heat range to the R5724-8 from NGK.

The IT27 is similar in heat range to the R5724-9 from NGK.

As an additional reference point, the production LSA/LS9/LS7 plug is an AC Delco 41-104 iridium plug. It is similar to an IT20 in heat range which is about the same as a TR6.

 

A lot of people use the stock wires with great success, but a quick search will turn up a bunch of results. GMPP has some that get good reviews though-

 

I looked into the wires i have and they have a good rating for noise cancellation. I'm sure i will run ngk, because that is what i was running before the lingenfelter box. Thanks again for all the replies.

 

No problem, let me know if you need anything else!

 

I have heard that magnecore makes a great wire that is low noise. You should not have much of a problem with noise on the OEM wiring and computer. Noise is a very real issue on aftermarket PCM's.

 

We have had very good results with the OEM wires and with the Magnecor wires.

 

Whatever you do, do not run any type iridium plug with nitrous. That is a recipe for disaster

 

can u run br7ef plugs with the lnc-2000 box?

these are the plug wires im running with br7ef plugs is it a good combo for the lnc-2000

 

Could you explain/clarify your reasoning for this?

We ran a 500 shot of nitrous on our 427 CID LS9 supercharged 2010 Camaro SS with the Denso IT27 plugs without any issues.

The GM production LSA/LS9/LS7 plugs are also an iridium plug and many people use these with spark plugs with nitrous.

 

Yes, the BR7EF plugs will work great with the LNC-2000. You shouldn't have any issues with that combo, there are lots of people running the exact setup!

 

Show me one real race car using an iridium plug. One that's fast and not consuming pistons like a fat kid with a bag of candy.

 

The BR7EF spark plugs are a resistor plug so they should be fine from an electrical noise standpoint.

They are a NGK 7 heat range.

You can usually find the specifications on the NGK plugs on the NGK web site here:
https://www.ngksparkplugs.com/

or directly here:
http://www.partcat.com/ngk

Be careful trusting the data on other web sites (non manufacturer web sites). I frequently find heat range, resistor configuration etc. errors for spark plugs on major web store sites.

 

All those are projected tip plugs. Why would you use a projected tip plug on nitrous?

 

And an iridium on top of that......

 

If it doesn't say br7ef, I don't use it.

 

If I put a 7 heat range in my motor it would be melted before the car got 300 feet.

I run a 10 or 11.
