Hey everyone,

I wanted to share a little tip I've been using to get the NGK racing plugs for cheaper than most of the online places.

They typically run deals twice a month like "$50 off $125" orders. Sometimes it's a flat percentage but most of the time it's $40 off $100 or $50 off $125. You can find them pretty easily with Google's help.

I'll search and order one of the varying options, such as the NGK 6725-11 (11.5 unavailable online at this time), and add 4 to the cart. NGK Racing Spark Plug 4311: Advance Auto Parts

Once I add them, I'll apply a promo code in the cart, the active one right now is WD523.

This takes the total from $37.99 x 4 = $151.96 to $101.96 or $25.49/ea spark plug *SHIPPED*.

It's not much but just wanted to share for anyone looking for a decent price on plugs with lifetime warranty through Advance (they don't care, they just replace them most of the time.)

Very helpful. 50 bucks off is 50 bucks off! Thanks, Aaron!

 

Seems like advanced auto parts doesnt carry the R6725 plugs anymore? Searching yield 0 results

 

They probably saw this thread and stopped offering them

 

Lol they are probably removing them but I have seen stock cycle some in the past and get removed and added again later on.

The promo code also cycles but usually it just increases one or two digits at a time. Several weeks ago it was WD523, it's probably WD524 the week after and WD525 after that and it keeps climbing. It started at WD500 and will probably go up quite a lot.

You'll have to convert the NGK6725-xxx heat range number into a four digit NGK number.

IE:
R6725-105 is 3857 - if you search Advance for 3857, they carry those.

Here's a quick reference map, they may or may not carry these:
R6725-115 - 4482
R6725-11 - 4311
R6725-105 - 3857
R7420-11 - 7756
R7420-105 - 4857
R7420-10 - 5501
R7420-9 - 6448
