As good as HKS M40XL Spark Plugs IF NOT BETTER!
N75 Motorsports will NOT sell HKS M40XL due to this product being as good for less than half the cost, we do not feel it is fair for the customer to be "fooled" by brand names, we used to sell and stock M45XL as they are the cheapest available 9 heat range plug, however M40XL is 8 heat range, this is the same as these, we do not believe it is fair for a customer to spend over double for basically the exact same plug if not a worse one. NGK Plugs are the standard in the automotive industry for the last 25 years+, from ultra high performance exotic cars, to daily drivers, to fleet vehicles, you will find NGK from factory.
FREE GAPPING SERVICE! LET US KNOW WHAT GAP YOU WANT WHEN ORDERING IN COMMENTS AND WE WILL GAP THEM FOR YOU, IF NO SPEC IS ASKED FOR, .025 WILL BE GAPPED TO AS THIS GAP WE HAVE HAD NO ISSUES ON STOCK CARS OR STUFFED TURBO CARS.

Great OEM Replacement, some people run these plugs with tunes! They are very good replace plugs if not tuned. At N75 Motorsports we do not recommend these for a tune, however we see HKS M40XL as a waste of money, these are basically the same plug at less than half the cost!
