    Fan relay for Honda Pilot and other Honda cars
  

*by A***. on Reviewed in the United Arab Emirates on 20 January 2024*

Excellent product. Do not get hot even when cooling fan runs continuously in hot summer in UAE.Good product

### ⭐⭐⭐⭐⭐ 







  
  
    Esupport 5 pin relays
  

*by J***6 on Reviewed in the United States on 14 August 2024*

Bought to use in a 2023 Royal Enfield Himalayan, Would not fit because that bike apparently takes 4 pin relays. So now these are spares for my 2022 Royal Enfield INT650 if my Bosch ones ever quit.Overall they feel exactly same as my Bosch ones do and they appear to work just as well and without issues.

### ⭐⭐⭐⭐⭐ 







  
  
    Good quality and good value
  

*by J***O on Reviewed in Canada on 24 February 2024*

But this because I needed them and they are good qualities and the value is really good on here
