Wesellcarparts has been having just as many issues getting them in stock.

Red, Wesellcarparts stated that HPS didn't change the ETA for the parts to be shipped this week so we should be "hopefully" be getting them this week.

I ordered my set thru wesellcarparts because of the bad customer service experience from Corsport. I feel I must give wesellcarparts props for the excellent and prompt communication so far

WSCP has been great on my orders, so no issue with them. I canceled my order through Corsport, but they were very professional in handling it and very upfront on what they didn't know.

Ordered mine this morning, I expect to have them next week.

I installed the tubes and took more temperature measurements. I don't see any difference in temperature between the HPS tubes and the stock plastic ones.....which is pretty much what I expected. There was speculation on here that the HPS tubes might be a better insulator and therefor help keep intake temperatures down. The temperatures still run about 8-10 degrees above ambient which I doubt any other CAI can beat. It finally warmed up to around 85 here and the intake temperatures ran at 95 while cruising at 60 on the freeway.

The car does seem to respond better with the HPS tubes + K&N drop ins as far as overall throttle response goes. BERK HFC's also went on today and seemed to really wake up the midrange which I didn't expect since I thought most of the benefit from HFC's was up top.

Great findings with the intake temp. Thanks for following up
