## Customer Reviews

### ⭐⭐⭐⭐⭐ For my lawnmower
*by  on Reviewed in the United Kingdom 22 March 2026*

Excellent product

### ⭐⭐⭐⭐⭐ Straightforward replacement
*by  on Reviewed in the United Kingdom 15 October 2023*

Dead easy to fit. You might find removing the top engine cover (the black plastic) makes removing the spark plug wire easier.Make sure you inspect the condition of the spark plug as usual when replacing!Don't stretch the foam when replacing the filter, especially the bottom section that squeezes into the air intake trap, as it may tear easily, just push it into the tight gap, it's meant to be quite resistant so that airflow goes around the length of the filter with that blockage at the bottom (You'll notice the actual hole to the outside at the bottom of the housing just to the left of where this pinch is).

### ⭐⭐⭐⭐ very easy to assemble. good.
*by  on Reviewed in the United Kingdom 5 March 2022*

This air filter fits well and the spark plug is a good quality, i like it.
