Snow Performance has combined performance, quality, and ease of installation in this new water-methanol injection kit designed for all turbo diesel owners who demand colder EGTs while towing heavy loads. The Diesel Stage 3 Boost Cooler utilizes a 2D mapped controller that commands injection based on boost pressure and EGTs (exhaust gas temperatures) to maintain extremely cold air inlet temperatures, 100-300 EGT decreases, decreased emissions, cleaner engine components, and increased fuel economy all while giving 65+ HP to help pull large hills with easy effort while towing. A must have for the diesel enthusiast that is concerned about the longevity of his truck that sees heavy towing. None invasive, the Diesel Stage 3 Boost Cooler controller is designed to mount on the steering column or the dash so no drilling/marring of the interior needs to take place or additional gauge pods need to be purchased. Functions as a boost gauge, water-meth controller and EGT monitor all in one! Concerned about warranty? The Snow Performance Stage 3 does not leave a signature on the vehicle leaving your diesel truck with its warranty intact. 7 Gal Tank included for trip ready installation. Recommended for all daily driven diesel vehicles that see heavy towing where EGTs become dangerously high. Need a CARB E.O.# for your state? No problem! This system is 50-State Legal!

Near OEM quality at 1/4 cost
Near OEM performance at 25% of the cost! Bosch Quality replaced NGKs/Toyota OEMs. Great value and now the engine is running smoothly! I have seen a slight improvement in my mpg @1mpg overall in mixed driving conditions.

Very Expensive
Had one cylinder misfiring so replaced coil and spark plug. Runs fine now, but old plug looked shot after only 5 months so I think the coil was the problem. Really good plug so far but very expensive.

A reliable set of spark plugs.
They’re made in Germany, what else can you say

Work as well as the NGK's
Bought for a 2016 Mazda 6, I had NGK's in it for 5 months and had misfires, didnt have the money to throw more NGK's at it for troubleshooting. Bought these to try and they work great so far.

Faulty plug? Otherwise great set
Definitely better than the old plugs that probably had 80k miles on them.
The one star off is because I had a misfire after installing. Not sure if I damaged the plug or what, but a reinstall didn't fix the misfire. In my genius, I rushed to try to gap it and ended up breaking the iridium tip. Put the old plug into cylinder 3 (where the misfire was) and it was fine.
Gonna have to get a new single tomorrow at my local shop, but a bit frustrating to get a misfire after install.
