Is there a recommended website to buy OEM air filter and cabin filter for 2014 base RLX. The dealers charge way too much. Thanks for your help.

If you must have OEM then utilize an online Acura parts vendor to save a little over the stealership.

If you can settle for cheaper aftermarket filters, find the exact OEM part number for the two filters & plug them into rockauto.com's 'Part Number Seach' and find much cheaper alternatives.

 

is rock auto parts quality? Or do you think they are not as good as OEM

 

Surely, one of the last three in the RA selection below is adequate to meet your needs versus overpriced OEM?
Look at how much you will save.

I have had a K&N air filter on my S/C'd 2003 CL-S6 & an inexpensive (Chinese) ebay serviceable hi-flow stock air box shaped filter on my CL-S automatic for years with no issues.

Now, when it comes to electronics / sensors & engine mounts, for example, one may want to pay the OEM premium; otherwise, don't 'hang yourself up' on all OEM, IMHO of course.

 

thanks

 

for cabin filter you can go with anything but for air filter i go with oem.

 

I've had good luck using Wix air filters and cabin air filters from RockAuto.com. They're essentially what OEM is - put them side-by-side and there's literally no difference.....

 

Another vote for RockAuto and Wix filters. No problems with them.
