Simple, straight forward answer, because they know people that know very little about engines will buy them. IPD has sold all kinds of products over the years that are absolute, dismal junk. Why? Because they make money doing so. I bought a 1993 240 that had a VX3 installed in it and had a free flowing exhaust as well. Other than having a lumpier idle, there was almost no difference between a stock 240 and that particular car. It might have made 10 more hp once it was way up in the RPM band. It felt no different accelerating than a stock 240. Somebody wasted over $200 on that 'mod". IPD still sells the MTC ignition switches that last anywhere from one week to one year, even though they have had many failures. I recently bought their guaranteed fit 240 wagon sun visor clips. $2 vs. $3 for OE. I thought, give them a try, how can anyone F-up a simple part like that? Well, they can. Whoever made the mold made the opening where the visor slips into the clip too small. Way too small. Attempting to lock the visor in place would result in ripping the vinyl off of the visor. I called them about it. The rep played dumb. "What is it about the clip that isn't correct?" I explained the problem. His response, "If you file material off of the opening they work fine". Caught lying to the customer. They knew exactly what they were selling. Pure junk. The point of this? I've been very dissatisfied with IPD for many years. There is a reason none of the original staff still work there. I have plenty of stories about their current culture and customer service that does not line up with what earned IPD a decent reputation in the Volvo community in the past.
