For all those who are running nitrous, or forced induction (blower or turbo), I'm curious what plugs you use? If you can, post up the part numbers and gap. Thanks!

NGK Copper V-Power LZTR5A-13 Spark Plugs for HEMI Engines (Set of 16)
SKU: 4306 (x16)

Big performance in a little package. These NGK V-Power spark plugs offer economical performance for nearly any automotive application, and are the only plugs with NGK's V-Groove technology. They enhance ignitability, lower the voltage requirement of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs also are highly durable against electrical and chemical wear, making them a long-life replacement plug. Because of the V-Groove, the spark occurs at the edge of the center electrode. So heat is not absorbed by the electrode itself. This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance.

Shorty Spark Plug: No
Resistor: Yes
Manufacturer Heat Range: 5
Electrode Core Material: Copper
Electrode Tip Material: Nickel alloy
Insulator Type: Projected
Spark Plug Thread Size: 14mm
Spark Plug Reach: 25mm
Spark Plug Seat Style: Tapered
Wrench Diameter: 5/8 in.
Ground Strap Quantity: One
NGK Part Number: LZTR5A-13 Quantity: Set of 16 Spark Plugs

PRICE: $47.95

Not sure brother...call Vortech

Shouldn't FI guys be running at least 1 step colder than stock? Heat range of stock plugs is also 5?

Turbo

LZTR6AIX-13 (6 heat range...one step colder than stock)

Gap = .030

Turbo

LZTR6AIX-13 (6 heat range...one step colder than stock)

Gap = .030

These are the plugs that I see most guys go with. Even in N/A applications. When I had just my 426 (no whipple), I was running these plugs without any problems. After I had my blower installed, I noticed the installer removed those EXPENSIVE plugs and changed them out to the ones 1BAMFR is running. I do not think these plugs are ideal for my setup. I am thinking of returning to the LZTR6AIX-13's or even LZTR7AIX-13's (2 steps colder) I am trying to become a better plug reader and after pulling a couple plugs today, I think my plugs are too hot. Also noticed the timing mark on my ground strap is closer to the threaded base than the tip indicating too advanced timing. If I run a colder plug, I may be fine with timing.

Josh @ HHP installed these plugs during dyno tuning. I'm sure they're in there for a reason!

The plugs I use are NGK LTR6A-11. Special order only.

I've been think of going with a colder plug too. I know Anthony (Grip Grip) is running two steps colder...not sure of his gap.

I've been looking for this plug and do not see it listed ANYWHERE! Where do you special order it? Is it really a non-projected tip? I can't find any specs on this plug.

Miamimac, in another post you stated:
"I read on another site to use two steps colder plug NGK LTR6A-11 gapped at 35. Hopefuly some of the more knowledgeable guys will chime in. If you want to read where I got it from PM me."
How are these plugs two steps colder if according to the numbers, it has a heat range of 6? Not saying you're wrong, maybe I don't understand the coding properly. A heat range of 6 in the NGK lineup will be the same for any plug whether it's a V-power, G-power, Iridium IX, etc, etc, right?

I read that on another site before I got into FI. I now know the "6" in the part number designates its heat range. HHP has the "7" listed on their site. Part # LZTR7AIX-13. I need to learn how to read plugs. Mine have a what appear to be brown stains which I'm asuming its cause I don't have a catch can and it might be oil particles?

WOW this is too complicated !!!!!

N/A people use what type?

and F/I use what type?

I think for N/A, stock plugs are good. The general consensus it that for Nitrous or FI you should go with 1 or 2 steps colder with a tighter gap.

OK, found this recent thread in another forum that answers a lot of questions concerning plugs for our Hemi.

I'm running two steps colder and I believe they're gapped to .035.

NGK Iridium IX LTR71X-11 (6510).
