Review on NGK 2633 Spark Plug by Leroy Jacobs

Thanks to my knowledge gained in practice I made the wise choice to replace my old spark plugs with this NGK model. The installation was hassle-free and the difference in performance was noticeable right away .The engine runs smoother and i can feel the added power behind the wheel. The only downside is that it's a bit costlier than other options on the market. Nonetheless, I highly recommend NGK spark plugs for any car enthusiast looking for an upgrade..
