Here I have for sale a BMW M50 Inlet Manifold annd throttle body.
This part can be used to increase the power of BMW 328s abd 323s due to the increased airflow offer by the larger diameter inlets.
If you type BMW M50 manifold into Google you will get loads more info.
It is suggested that simply fitting this manifold to a BMW E36 or E46 328 can give an increase in power of approx 20 bhp.
If you check out ebay you will see that on average these sell for between £70 and £100 so grab yourself a bargain.
£50 cash on collection preferred.
I may consider posting it but the price would be £70 to cover postage and Paypal charges.
