I still stand by my US made Bosch unit.
$200 through DPP? Sheesh.
How long and how many miles has it been running on your truck…it IS less expensive then the oem pump.
Must have gone up in price recently…I paid $159 for mine, still expensive, but IMO worth it compared to having to replace in 30 to 50k, which is what it seems many aftermarket water pumps only last.
